Model Residual Stress by Finite Element Method

Abstract

This paper presents an original model developed by finite element method to simulate the behavior of the material to the method “Blind Hole Drilling”, to determine the residual stress. Modeling of this method is possible through the use of the “Birth and Death” which have some elements of ANSYS library. After obtaining the analysis of movements, appropriate loads, a node located from the center hole at a radius calculated. In this way it is easier to estimate the stresses and deformations of a piece. Several measurements are made and based on this model is given in ANSYS. In this way we can have a map of tensions and deformations in a material
