stress solid element

Then two schemes are presented to reduce the false stress in a transition element connecting an axisymmetric solid element to an axisymmetric thin shell element for axisymmetric stress analysis.

方案一是在采用体元应力应变模型的基础上提出了一种单元内位移、应变及应力的直接修改方法；

The reason for generating the false stress in a transition element connecting a solid element to a thin shell element for stress analysis is considered.
