abaqus中平面应变和广义平面应变单元的区别
下面是ANSYS官方帮助文档中的内容。
Generalized plane strain is similar to plane strain, except that the Z direction strain is not required to be zero. The Z direction strain may vary linearly in the X and Y directions (but not in the Z direction), removing the implied restriction of plane strain that the model extends without limit in the Z direction. The model in the Z direction can also have a uniform curvature.
Generalized plane strain can be used for modeling a section of cylindrical geometries, or to model long structures with a load at the end.
The generalized plane strain feature assumes a finite deformation domain length in the Z direction, rather than the infinite value assumed for standard plane strain. Generalized plane strain, therefore, gives more practical results for deformation problems where the Z-direction dimension is not long enough. It also offers a more efficient way to simulate certain 3-D deformations using 2-D element options.
