principal shear strain

基本解释

The strain criterion for ductile shear failure based on the maximum principal shear strain is established.
据此，建立基于最大主剪应变的岩土材料延性剪切破坏应变准则；
The formulas of the maximum principal shear strain are deduced; and the calculation cases for several commonly used yield criteria are presented.
最后，详细推导出最大主剪应变的计算公式，并针对几种常用屈服准则给出计算示例。
An equation for the calculation of true shear strain was derived from the integration of infinitesimal shear strain in plane shearing process with constant principal shear strain direction.
对切应变主轴不变的平面简单切变过程，通过无穷小应变的积分，导出了真实切应变计算公式。
