A Phase Transition Model Describing Auxetic Materials
2017In this paper we introduce a newmodel describing the behavior of auxetic materials in terms of a phase-field PDE system. More precisely, the evolution equations are recovered by a generalization of the principle of virtual power in which microscopic motions and forces, responsible for the phase transitions, are included. The momentum balance is written

Poisson's ratios of auxetic and other technological materials
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2010Poisson's ratio, the relation between lateral contraction of a thin, linearly elastic rod when subjected to a longitudinal extension, has a long and interesting history. For isotropic bodies, it can theoretically range from +1/2 to -1; the experimental gamut for anisotropics is even larger.
