Stress Analysis of a Thick Plate

This is a benchmark and validation model for linear elasticity where an elliptical thick plate with a hole is subjected to a uniform pressure load of 10⁶ MPa [1]. The outer surface is assumed to be constrained from expansion, in addition to the center line which is fixed in the z-direction. Symmetry is also utilized so that only a quarter of the geometry is modeled.

This model is available as an automated tutorial by selecting Model Examples and Tutorials… > Structural Mechanics > Stress Analysis of a Thick Plate from the File menu. Or alternatively, follow the linked step-by-step instructions.
