- Here, we demonstrate a method to create material models for anisotropic, auxetic materials. The method can replicate material properties to any prescribed degree of accuracy and, when used in finite element models, requires much less computational time than conventional models. This work furthers understanding of naturally occurring and manmade auxetics. Specifically, the method can create models for auxetic foams, as demonstrated in the paper, useful for protective equipment, footwear and prosthesis, and auxetic biological tissues or scaffolds for medical devices and surgical procedures. We established an international collaboration with the co-authors based in Madrid, and are modelling more materials together.
