WebIn this study, the substructure is considered based on the crystal plasticity (CP) method which is a well-established approach to predict the mechanical responses of crystalline materials . This method takes into account crystallographic anisotropy and captures the underlying physics at the crystal level [ 16 ]. WebFor single-crystal plasticity, the most important internal variables are the dislocation densities on various glide planes. Their evolution is governed by balance equations involving production and annihilation rates. Dislocation interactions determine in a basically anisotropic way the slip rates and the evolution of the critical shear stresses. WebWritten by the leading experts in computational materials science, this handy reference concisely reviews the most important aspects of plasticity modeling: constitutive laws, phase transformations, texture methods, continuum approaches and damage mechanisms. chirine youtube
