Phase Field Theory and Analysis of Pressure-Shear Induced Amorphization and Failure in Boron Carbide Ceramic
A nonlinear continuum phase field theory is developed to describe amorphization of crystalline elastic solids under shear and/or pressure loading.An here order parameter describes the local degree of crystallinity.Elastic coefficients can depend on the order parameter, inelastic volume change may accompany the transition from crystal to amorphous p
