摘要

Crazing process in rubber particle modified glassy polymers is numerically simulated by using micromechanics and finite element methods. To simulate the initiation and growth of craze, craze elements are prearranged in the unit cell mode, in which Drucker-Prager's plastic constitutive relation is employed to describe the deformation behavior of craze elements. Modified Sternstein's criterion is used as the initiation criterion of craze in which effect of hydrostatic stress is considered. Effect of craze on the macroscopic deformation behavior of polymer is discussed. Moreover, effects of the volume fraction of rubber particle and craze on the macroscopic deformation of polymers are discussed in detail.
