Inverse design of mechanical metamaterial achieving a prescribed constitutive curve

Theoretical and Applied Mechanics Letters
Besides exhibiting excellent capabilities such as energy absorption, phase-transforming metamaterials offer a vast design space for achieving nonlinear constitutive relations. This is facilitated by switching between different patterns under deformation.
