| Outline of Final Research Achievements |
Mathematical modellings and numerical simulations of morphing structures such as a composite annular sheet or an elastic bilayer have been developed in the framework of nonlinear elasticity. It reveals that the combination of the material and geometrical properties can tune the shapes after deformation in response to external stimuli. The composite sheets can morph from a flat annular sheet into a saddle shape with ripples at the outer rim by tuning the shrinkage size and the relative hole size to the system scale as well as the elastic stiffness contrast. The elastic bilayer can also morph from a flat surface into a wrinkled surface by controlling the elastic modulus ratio and thickness ratio between the film and substrate. The proposed framework could be applicable to design a bionic morphable device harnessing the bulk and surface morphing.
