In addition,the thickness of band is determined according to the maximum local plastic shear strain. Local plastic shear strain and local plastic shear displacement analytically obtained show that these two local parameters increase with strain rate.
将断层岩爆简化为一维动态剪切问题，利用：局部塑性剪应变的对称性；在断层带的边界上，其应变值为零；断层带的宽度由塑性剪切应变取极值来确定等条件，得到了断层带内部的局部塑性剪切应变及局部塑性剪切位移，二者都随应变率的增加而趋于明显增加。
