Plane Stress: Plate with Circular Hole in a Tensile Field

This tutorial demonstrates how to set up a linear elastic FE (Finite Element) stress analysis in Simcenter STAR-CCM+.

The case under study is a rectangular plate under axial loads. A circular hole at the centre of the plate causes stress concentrations. The plate is in a plane stress state, so the stresses perpendicular to the plate are zero.

In this tutorial, you compute the stresses and the stress concentration factor at the hole and compare them with an analytical solution from Roark's [992].

The mathematical model is schematized below.

Length L = 1.20 m
Height h = 0.7 m
Thickness t = 0.01 m
Hole Radius r = 0.15 m
Axial Load T = 1000 MPa
Material Al
Stress condition Linear elastic

As this problem has double symmetry, it is sufficient to model a quarter of the plate in Simcenter STAR-CCM+.
