Plane Stress in a Plate With a Hole

AJ Baker, University of Tennessee, Knoxville

The plane stress analysis of a square plate with a hole at the center subjected to tension is performed using COMSOL Multiphysics.

Objectives of this simulation:

1. Evaluate the use of COMSOL Multiphysics for an analysis of a square plate with a hole at the center subjected to tension.
2. Verify the base problem solution on the given mesh and observe the von Mises stress concentration distribution.
3. Refine the base mesh and check the accuracy of this solution.
4. Via computational experiment, determine the shape of the non-circular hole of the same area as the circle that generates the minimum stress concentration in the plate. Use solution-adapted mesh refinement in areas predicted to exhibit extremum von Mises stress concentrations.
