Finite Element Analysis of Investigation of Bars with Semi-Circular Notches

Abstract

In this thesis the effect of semicircular notches under bending in a bar and the stresses are investigated for different materials using finite element analysis. The notch radius taken are 2mm and 3mm. The notches are taken at end of bar and at 3mm from end of the bar. The different materials considered for the analysis are Aluminum alloy 7075, composite materials S2- Glass Epoxy, Kevlar 29. The model is created by using CREO 2.0 and structural, fatigue and modal analysis results are obtained by using ANSYS
