各向异性的材料 meaning in English

anisotropic material

The thesis analyzes the inner cracking reason for the hot rolled sheet based on texture orientation transformation , simulates the forming process of drawing sheet by the barlat - lian anisotropic yield criteria , and discusses the cracking mechanism in the deforming and stress distribution
本文由该材料的微观织构取向变化分析造成板开裂的内在原因，根据能够准确描述塑性各向异性的材料模型，模拟了冲压板开裂圆件成型过程，由其变形分布和应力分布探讨开裂机理。
But the precondition of this method is that the material must be the elastic isotropy . for the elastic anisotropy , because of the difference in the each direction of mechanical properties , actually , the result of the nanoidentation load - displacement data is the synthesis of the mechanical properties in every direction
但是这种方法的一个前提是各向同性的材料，对于各向异性的材料，因为机械性质在各个方向上不同，所以在一个方向上的压痕试验结果实际上是各个方向不同材料性质的一个综合值。
