论文摘要
我们提出了线性弹性 - 完美塑料材料中准静态裂纹生长模型的数值实现。我们假设位移是抗平台,并且裂纹和塑料滑动位于规定的路径上。我们提供了以下事实的数值证据:裂纹生长是间歇性的,其跳跃特性取决于材料特性。
We present a numerical implementation of a model of quasi-static crack growth in linearly elastic-perfectly plastic materials. We assume that the displacement is antiplane, and that the cracks and the plastic slips are localized on a prescribed path. We provide numerical evidence of the fact that the crack growth is intermittent, with jump characteristics that depend on the material properties.
