strain localization band的意思|示意

A theoretical analysis of localized strain and strain rate in shear band after localization occurs beyond the peak shear stress is carried out based on the strain gradient plasticity theory.

应用应变梯度塑性理论对局部化剪切带内部(塑性)剪应变(率)规律进行了理论分析。

Under plane strain condition, the strain localization starts around the peak stress state; and a V-shaped shear band is formed at the residual stress state.

在平面应变压缩条件下，砂土在峰值应力状态附近出现应变局部化现象，在残余状态最终形成一条V型剪切带。

The finite deformation theory and the Nakai's sub-loading constitutive model are used to investigate shear band localization in plane strain model tests.

基于有限变形理论和中井的下负荷面本构关系模型，研究了平面应变试验中黏土试样变形的局部化问题。

Furthermore, the localization shear band bifurcation takes place at the point in the strain softening area, and the point would be far from the peak point with the increment of lateral pressure.

此外，岩石材料的剪切带分叉发生在峰值应力之后，随围压增加而逐步远离峰值点。

The strain localization on a shear band induced by post-peak softening is one of the most important deformations and strength characteristics of sand.

这种由软化特性引起的应变局部化剪切带是砂土材料非常重要的变形和强度特性之一。

The trace algorithm proposed does not request the continuity of strain localization propagation paths, and the interaction among localization band segments can be taken into account.

该算法不要求追踪路径的连续性，并可充分考虑各局部化带间的相互影响。
