ABAQUS帮助中对于单元特征长度如何选取有如下描述：
The definition of the characteristic length depends on the element geometry and formulation: it is a typical length of a line across an element for a first-order element; it is half of the same typical length for a second-order element. For beams and trusses it is a characteristic length along the element axis. For membranes and shells it is a characteristic length in the reference surface. For axisymmetric elements it is a characteristic length in the r–z plane only. For cohesive elements it is equal to the constitutive thickness. .
敦大侠，谢谢您的分享经验和体会；在这方面，我还是一些不明白，想问问您：1、等效塑性应变如何求解？我在ABAQUS的帮助文档例题2.1.16 Progressive failure analysis of thin-wall aluminum extrusion under quasi-static and dynamic loads中aluminum的等效塑性应变为什么先减小后增大。。。。。期待您的回复敦大侠，O(∩_∩)O谢谢
