Dear imechanicas,
When composite plates with cutouts are meshed, the mesh scheme around the hole is somehow not in a mapped shape. This means the edges of (for instance a four-node element) in undeformed shape are not in a rectangular format. Therefore, defining the constitutive equations of orthotropic materials might lead to incorrect results.
Does anybody have opinion/experience about this issue?
Any response is appreciated.
