Triply periodic minimal surfaces are cellular structures that naturally inspired continuous non-self-intersecting surfaces similar to bone microstructure with controllable mechanical properties. In this work, sandwich composite panels constructed from four different types of TMPS unit cells and metallic facets are numerically investigated and compared to evaluate the dynamic behaviours when subjected to extreme loadings. The finite element analysis is utilised to simulate the deformation of proposed structures considering the rate-dependent properties, elastoplastic response and nonlinear contact. The Johnson–Cook material model is implemented to capture the transient responses of the four T..
