Abstract

In this paper, we present topology optimisation formulation considering material and geometrical nonlinearities based on the Updated Properties Model (UPM). We use the Saint Venant and neo-Hookean strain energy for physical nonlinearity and the Green-Lagrange strain tensor for geometrical nonlinearity. The suggested method can be applied to the effective design of hyperelastic metamaterials, with the primary potential applications being in biomedical and soft robotic systems.
