摘要

以各向同性Mohr-Coulomb剪切屈服准则为基础，研究了各向异性剪切屈服准则的一般理论方法。在此基础上，对正交各向异性的剪切屈服准则及其数值实现方法进行了研究，利用FLAC3D数值分析软件中的FISH语言编制了相应的计算程序，并引入FLAC3D中。理论分析和数值计算分析表明，正交各向异性剪切屈服准则与3个主应力均有关，各向同性剪切屈服准则为其特例，各向异性材料的屈服面不一定与最大剪应力面重合。

Abstract

The theory and methods of anisotropic shear yield criterion is studied on the basis of isotropic Mohr-Coulomb yield criterion. The above theory and methods are applied to establish orthotropic shear yield criterion and to analyze the way to introduce it into the numerical analysis. In order to introduce the orthotropic shear yield criterion into FLAC3D

the codes are developed by using the FISH language of FLAC3D. Theoretical analysis and numerical analysis indicate that the orthotropic shear yield criterion is related to 3 principal stresses and the isotropic shear yield criterion is a special case of the orthotropic shear yield criterion. The analysis also shows that the maximum shear stress plane can not be the same of yield plane in orthotropic materials.
