My research is focused on the idea of forming surface features in the shell and combining this effective anisotropic ‘texture’ with prestressing. These novel prestressed textured shells provide a great variety of possibilities for the design of morphing multistable structures, where the structure can be repeatably transferred between distinctive stable configurations. For instance, they can be used in deployable structures, or in reconfigurable aircraft where the geometry of the structure can change in order to have more efficient flight configuration. Remarkably, the computational and experimental results in this study have shown that dimpled textured shells can achieve an effective Poisson’s ratio in bending of close to -1, illustrating a strong coupling between bending in two orthogonal directions and reinforcing the potential of using these textured shells as multistable structures.
