EPSRC DTP Studentship - Long-span timber-hybrid cellular beams for more sustainable structural design

Jobs @ Department of Engineering - Wed, 20/03/2024 - 00:00

Reducing the environmental impact of the built environment requires more sustainable structural design. This means using better structural materials and using structural materials better. Achieving efficient, constructable solutions for floor systems that require both long spans and flexible service layouts has been a barrier to the adoption of new lower net carbon materials, such as engineered timber, in the commercial building sector worldwide. The aim of this project is thus to develop, test and produce design guidance for timber-hybrid cellular beam solutions for long-span floor systems.

During this research, you will use a combination of analytical, numerical and experimental research methods to understand the behaviour of timber-hybrid cellular beams and then use this understanding to inform design. You will have the opportunity to investigate novel timber-hybrid cellular beam concepts proposed by industrial partners and to develop your own design solutions.

You will be part of a supportive research group that embraces diversity and enables flexible working. We are centred in the new Civil Engineering Building which accommodates both state-of-the-art lab spaces and a vibrant community of research students, researchers, academics and more.

Applicants should have (or expect to obtain by the start date) at least a good 2.1 degree in an Engineering or related subject. Knowledge or experience of structural analysis, numerical modelling and/or experimental testing is desirable. Industrial experience is welcome but not expected. A background in timber engineering is similarly welcome but not expected.

EPSRC DTP studentships are fully-funded (fees and maintenance) for students eligible for Home fees. Full eligibility criteria can be found via the following link; https://www.postgraduate.study.cam.ac.uk/finance/fees/what-my-fee-status

EPSRC DTP Studentship - Vibration Isolation of Buildings and the Impact of Soil-Structure Interaction

Jobs @ Department of Engineering - Wed, 13/03/2024 - 00:00

Significant progress has been made in recent years in understanding the behaviour of vibration-isolated buildings, with research in Cambridge having considered various aspects of the vibration source, the transmission paths and the building itself. This project aims to advance our understanding to the point at which practicable design guidance may be formulated. The project has three primary objectives.

Quantifying Soil-Structure Interaction: A range of theoretical studies will be undertaken to quantify the effect of constructing a foundation in the vicinity of an underground railway tunnel. This will include extending recent work on the dynamic behaviour of piled foundations to account for layered soils. A range of semi-analytical and numerical models will be used.

Simplified Models for the Prediction of Base-Isolation Performance: A range of simplified models will be developed based on current research into effective building/foundation impedance modelling. This will take advantage of the findings of recent power flow analysis, which has highlighted the dominant vibration transmission paths and helped establish the acceptable modelling assumptions that may be made to enhance computational efficiency.

Design Methodology: An outline design methodology will be developed to cover the measurement (or prediction) of free-field vibration levels, the accounting for building and foundation structures and the prediction of the final isolation performance. The focus will be on a practicable methodology, supported, where necessary, with computationally efficient tools that are suitable for practitioner use.

The research will be conducted in close collaboration with CDM-Stravitec, a leading supplier of vibration isolation products.

Applicants should have (or expect to obtain) a 1st class, or high 2:1, honours degree in Mechanical or Structural Engineering. Preference will be given to those with experience in Structural Dynamics.

Fri 08 Mar 15:00: Conceptual structural design via graphic statics for the generation of materially-efficient, structurally expressive architectural forms.

Structures Group seminars - Fri, 01/03/2024 - 17:02
Conceptual structural design via graphic statics for the generation of materially-efficient, structurally expressive architectural forms.

Talk Abstract: Integrated architectural design takes into consideration various parameters at an early stage for the development of optimised buildings. One of these is naturally structural performance. In other words, integrating structural performance in the early conceptual design stages can lead to significant material efficiency as well as aesthetic quality. This presentation will focus on how form-finding frameworks, and in particular graphic statics, can play a crucial role in integrated design and how it can enable the collaboration between architects and engineers. Relevant research conducted at CUED will be showed along with recent examples of applying these methods to projects at Foster + Partners.

Fri 15 Mar 15:00: Acoustic Emission Data Analysis in Concrete Fatigue and Fracture: An Entropic Perspective

Structures Group seminars - Fri, 01/03/2024 - 09:30
Acoustic Emission Data Analysis in Concrete Fatigue and Fracture: An Entropic Perspective

ABSTRACT :

Concrete may appear as a boring material on a macroscopic level. However, the concrete fracture process exhibits an interesting complex behaviour dominated by disorder, long-range interactions, and long memory in the intensified stress field ahead of the crack tip known as the fracture process zone. The fracture process resulting from such complexity usually generates long-tailed distributions leading to self-organization signifying the emergence of order from the disorder. The existence of self-organization also hints at a universal pattern dominated by simple governing rules, regardless of system configuration. Consequently, entropy can be used as a measure of disorder to quantify the randomness of the probability distributions arising from the system variable. In this study, we propose cumulative distribution functions for acoustic emission features derived from Tsallis’ non-extensive entropy formulation. The Tsallis entropy is well-suited for modeling long-tailed distributions due to its sensitivity to the tail behaviour. Furthermore, the non-linearly interacting multi-scale cracks in the fracture process zone of concrete are inseparable and the whole system cannot be divided into simple sub-systems without tampering with the systemic properties, resulting in non-additivity and non-extensivity.

An experimental investigation was conducted to acquire acoustic emission data from the concrete fracture process. The testing involves three different sizes of notched plain concrete beams under three-point bending subjected to monotonic and fatigue loading. Two features of the AE stress wave, amplitude (magnitude) and inter-event time appear to be correlated with crack size and crack occurrence rate respectively. Distribution functions derived using the Tsallis entropy formulation are then fitted to the experimental data and compared across the beam sizes and loading conditions. The pattern in the collective behavior of entropic indices evaluated from the AE distribution is illustrated to highlight the possibility of self-organization. Monotonic loading controlled by crack mouth opening displacement allows stable crack growth resulting in critical AE distribution parameters that are used as a reference to track the damage evolution under sub-critical fatigue loading.

KEYWORDS : Concrete, Fracture, Fatigue, Acoustic emission, Tsallis Entropy

SPEAKER BIO :

Dr. Nitin Burud is currently working at the University of Surrey as a post-doctoral researcher. He received a doctorate from the Indian Institute of Science, Bangalore, India. His research work focuses on fracture and fatigue in materials, specializing in structural health monitoring applications using statistical data analysis. He worked extensively on acoustic emission techniques for understanding the fracture process in concrete-like cementitious materials. Consequently, his doctoral dissertation is a thematic exploration of acoustic emission data for mechanistic as well as statistical description, diagnosis, and prediction of damage evolution in concrete. Bringing a complexity perspective to understand the fracture process in concrete, and the use of Tsallis entropy as a measure of the complexity, is a central idea of his recent research. Before joining the University of Surrey, he shortly worked as an assistant professor at a deemed university in India. At the University of Surrey, he is investigating the fatigue behavior of a 130-year-old railway bridge through large-scale testing and numerical modeling.

EPSRC iCASE Studentship - Turbomachinery for Future Energy Systems

Jobs @ Department of Engineering - Thu, 22/02/2024 - 00:00

Decarbonizing the global economy can only be achieved by reducing the carbon intensity of energy sources. A key to achieving this is reducing the techno-economic barriers to replacing fossil fuel usage with low carbon and renewable sources. Solutions which reduce plant costs, improve plant efficiency, and increase plant flexibility with other energy sources, are key to delivering the UK Net Zero target.

This project addresses this by developing design methods to improve the performance of turbomachines operating with non-conventional or 'advanced' fluids, which can be used to reduce energy demand and improve energy efficiency. These advanced fluids include dense-gases (such as organic vapours) and supercritical fluids (such as super-critical CO2) and are fundamental to low-carbon energy systems using Organic Rankine Cycles and sCO2 cycles. These systems are important for a range of technologies including Heat Recovery and CHP, Carbon Capture, Hydrogen Gas Turbines and Renewables. Advanced fluids can be used as working fluids for heat management systems and to augment the performance of a gas-turbine prime mover. By exploiting the very high-power densities achievable with high pressure advanced fluids, these systems can be relatively compact and therefore minimize overall system cost and size. The project will use high fidelity simulations (Direct Numerical and Large Eddy Simulation) to investigate turbomachinery flows with advanced fluids (such as super-critical CO2).

Applicants should have (or expect to obtain by the start date) at least a good 2.1 degree, preferably at masters level, in an Engineering or related subject.

EPSRC DTP studentship - Engineering Interfaces: Charging Catalysts Efficiently for Improved Fuel Production

Jobs @ Department of Engineering - Wed, 21/02/2024 - 00:00

Engineering Interfaces to Efficiently Charge Catalysts

With the emergence of low-cost renewable energy sources and our societal push for decarbonization, it has become attractive to utilize renewable electrons to drive important industrial reactions such as ammonia synthesis and hydrogen production and to address issues related to sustainability such as emissions capture and conversion. However, conventional porous catalytic materials currently in use are designed for thermal processes, and they are inefficient in storing and using charges at the catalytic interface to affect reaction performance. Our research group has the capability to engineer these catalytic interfaces to improve electron transport and storage using a robust atom-by-atom deposition methodology inspired from thin film technologies such as Atomic Layer Deposition (ALD) and Self-Assembled Monolayers (SAM). This methodology improves over conventional methods of incipient wetness that have issues related to large crystallite formation and irregular structures, leading to an inefficient use of materials.

In this studentship, you will engineer nanostructures and investigate their catalytic properties under charge modulation for reactions involving fuel generations. The theme, as you have noticed, is efficiency i.e. efficiency in utilizing materials and efficiency in storing energy. Therefore, your work will include both exciting proof of concept studies and wider exploratory studies related to industrial applications. The advancements you make will have a major impact on UK's pursuit for decarbonization. Throughout the studentship, we will develop the research objectives over time, with the central theme focusing on engineering interfaces. You will have the opportunity to work with world-class experts at Cambridge and at other national and international institutions.

Informal enquiries to tmo32@cam.ac.uk are warmly encouraged.
