Hello Everybody,

I've been doing structural analysis of Composite plate using the element SOLID46. It's a quarter-plate method where the plate has 16 layers symmetric about the thickness.
The dimensions are 100 x 100 x 2.032 mm and fine to coarse meshing was used.

Symmetric boundary conditions along X and Y axis were applied to two edge surfaces of the plate while a structural displacement uniform load of 1 mm was applied to the other two surface edges.

In General PostProc, the Contour plot of DOF solution along X direction resulted in distortions along the edges where structural displacement uniform load were applied. It also occurs along Y direction.

I'm not able to account for this distortions.
Ansys APDL was used for the entire procedure.

Thank you
