| 摘 要： | 在众多复合材料宏观强度准则中,LaRC准则从复合材料失效机制出发,建立多个应力与强度的关系式来描述材料不同损伤模式的失效行为,其中LaRC03版本采用了平面应力假设,而LaRC04版本则将该分析方法推广至三维应力状态,LaRC05版本则对LaRC04版本进行了简化,增强了该准则的实用性。本文介绍了LaRC05强度准则及其在Abaqus有限元分析中的应用,并举例说明。

| Abstract: | As one of several macroscopic strength criteria for composites, LaRC considered complex stress states and failure models. LaRC03, based on Plane stress, are extended to account for three-dimensional loading (LaRC04, consisting of 6 expressions). LaRC05 is much more simple and practical, which has been implemented into Abaqus as the example. |
