1·Both the tangential modulus and secant modulus are exponential with axial strain.

松散岩块的切线模量和割线模量均与轴向应变呈指数相关性。

2·Based on lots of tube bending experiments, the stress-strain state along the tangential direction of bending line and the direction of the wall thickness is analyzed.

通过大量管材弯曲试验，分析了沿弯曲线的切向和管壁厚方向的应力应变状态，给出弯管内、外侧管壁厚变化量和切向应变的近似计算公式。

3·Centripetal force and tangential force or centrifugal force and tangential force could be used as a strain analysis method.

用向心力和切向力或离心力和切向力进行胁变分析是可行的。

4·In order to reflect the non-coaxial phenomenon, a non-coaxial plastic strain rate term is added to the tangential direction of conventional constitutive model's yield surface.

通过在屈服面的切线方向增加一项非共轴塑性应变增量，即可实现对非共轴现象的反映。
