CASE II Stress in a plate with a hole

For this case, the grid must match in the edges. The edges are defined as arcs. Some changes in the values are done to see how the mesh is altered.

The grid

Original generated grid


Initial values for undeformed semicircular shape


Values for a deformed semicircular shape


Original grid in green and modified in red

Results

Original sigma


Sigma for the deformed mesh


Original D magnitude
