APPLICATION OF ELASTOPLASTICITY COUPLED WITH DAMAGE IN STRAIN LOCALIZATION ANALYSIS
弹塑性损伤模型在应变局部化分析中的应用

Nonlocal constitutive models are widely used for effectively simulating strain localization. The major models may be classified into the following two kinds: the weighted-area-averaged nonlocal model and the gradient-enhanced-nonlocal model. Comparison between the two models is made in this paper. It is found that the Aifantis model is a reasonable choice for numerical simulation of a localized non-homogeneous material, but it is subject to some improvements.
