Abstract
It is necessary to determine stress and strain concentration factors around the circular notch in order to determine the site of crack initiation. The through-thickness variations of stress and strain concentration factors for plate contains a central circular notch subjected to biaxial loading have been investigated by using three dimensional finite element method (3D FEM). To study the effect of Poisson’s ratio (v) on elastic stress/strain concentration factors around the circular notch, four different values of Poisson’s ratio (v), varied from 0.1 to 0.4, have been studied numerically.
It is found that the maximum stress and strain concentration factors increase with increasing the Poisson’s ratio (v). The stress and strain concentration factors increase with decrease the biaxial ratio. Furthermore, the effect of Poisson’ s ratio (v) on stress and strain concentration factor decreases with increasing the biaxial ratio.
