deformation bands

It traverses the characteristics of the microstructures of faulting tectonics, including wavy extinction, deformation bands deformation lamellae, subgrains, dynamically recrystallization grains etc, and also studies their forming mechanisms in primary. 3.

详细研究了区内断裂构造的显微构造特征，包括显微裂隙、波状消光、变形条带、变形纹、亚颗粒、动态重结晶颗粒等，并对其形成机制进行了初步解析。

The plastic dilatable constitutive relationship of finite/ large deformation theory is used in present paper to analyze anti symmetric deformation of a marble. The stress formula, the eigenvalue equation and the condition that shear bands generate are obtained.
