Non-linear Plane Stress Analysis Using the Finite Element Method

Purpose of the Study The objective of this report is to check the Neuber and Linear rules, and to find the percent differences in comparison with the plane stress and plane strain solution using the non-linear finite element method. All the data are based on the maximum stress concentration where the crack forms and the material behaves non-linearly. This particular problem has been solved using ANSYS, which is a general purpose finite element program. Life Prediction Another purpose, which is not the main subject of this report, is to use the result from Neuber and Linear rules to predict the life of the structure in the crack initiation phase, using the Strain-Life curve (refer to chapter II for more detail)
