A deformation-dependent mixed-mode Poisson’s ratio can be achieved with the capability of transition from positive to negative values in both in-plane and out-of-plane directions, wherein it can further be programmed to have a wide-ranging auxeticity as a function of the microstructural geometry. ![]() Transition to the contact phase as a function of far-field global deformation can be designed through the material's microstructure. It is revealed that the metamaterial can transition from a phase of low stiffness to a contact-induced phase that brings forth an extensive rise in stiffness with programmable features during the deformation process. Mixed-mode deformation behaviour of the proposed metastructure involving both rigid origami motion and structural deformation has been realized through analytical and computational analyses, supported by elementary-level qualitative physical experiments. This paper develops kirigami-inspired modular materials with programmable deformation-dependent stiffness and multidirectional auxeticity. ![]()
