[探讨]Question 1: why the displacements in 2D analysis are a little bigger than that in 3D analysis? [复制链接]

Thank for "geofem" and "benjackxu"
In 2D plain strain analysis, it is assumed that strain in z direction is zero and shear sigma zx , sigma zy are zero.
How's the shear affect?  As "geofem" said  that is "three-dimensional effect'. How is the "three-dimensional effect'?  W\tSXM-Hg
