本文将作者最近提出的一种考虑角点效应的高阶应变梯度塑性理论修正为适合于其几何扩展的形式。它是假设的自由能增加的缺陷能量,具有非二次依赖于塑性应变梯度。通过对一个受约束的简单剪切问题和一个包含塑性流动局部化的平面应变拉伸问题的有限元分析,检验了扩展理论的预测特性。
A higher-order strain gradient plasticity theory with a corner-like effect, which was recently proposed by the author, is updated to a form suitable for its thermodynamics-based extensions. It is assumed that the free energy is augmented by a defect energy that has a non-quadratic dependence on the plastic strain gradients. Predictive feature of the extended theory is examined via finite element analyses of a constrained simple shear problem and a plane strain tension problem involving plastic flow localization.
