Impact–induced phase transitions in thermoelastic solids

Impact–induced phase transitions in thermoelastic solids

A continuum model of the macroscopic behaviour of solids capable of undergoing displacive phase transitions is applied to determine the response of such materials to mechanical loading by impact. The solid is modelled using one-dimensional finite thermoelasticity, and the model incorporates both a k...

Zusammenfassung:A continuum model of the macroscopic behaviour of solids capable of undergoing displacive phase transitions is applied to determine the response of such materials to mechanical loading by impact. The solid is modelled using one-dimensional finite thermoelasticity, and the model incorporates both a kinetic relation and a nucleation criterion controlling the evolution and initiation of the phase transition, respectively.
