摘要: Abstract A method for solving small strain plasticity problems with plastic deformation arising from the evolution of a collection discrete shear transformation zones (STZs) is presented. The STZs are represented as transforming Eshelby inclusions. At each instant, superposition used to represent solution in terms inclusions, which given analytically an infinite elastic medium, and image that enforces prescribed boundary conditions on finite solid interest. problem corresponds standard linear value problem. Constitutive relations specified kinetics transformation. general three dimensional formulation given. Solutions compression plane block presented illustrate potential framework.
