Objective
To verify the behavior of the MTC4 thick plate bending element in a skew shape
Problem Description
A skewed, simply supported plate is loaded with a uniform pressure load of 1 psi.
Material properties: E = 1e5 psi, ν = 0.3
Geometric properties: L = 100 in, h = 1 in
Finite Element Model
16, 64, 256, 1024 shell elements
Model type: 2D Plate Bending (MITC4 thick plate formulation)
Results
The displacement at the plate center (C) is given by [Ref 1].
Unit: displacement - in
