Analysis of stress concentration at the edge of hole in plates with different widths by using FEM

Abstract

Abstract The aim of this work was to investigate the concentration of stress due to circular cut out in sheets under tensile loads. Geometrical changes and loading create stress concentration. Under this condition, stress has increased in the regions of geometrical changes and if its value exceeds yield stress, the material fails in these regions. In this work, the distribution of stress in sheets with circular cut out was numerically investigated to study stress concentration at the edge of hole and the obtained results were compared with analytical solutions. In addition, relationships among stress concentration factors and relative dimensions of hole were determined using the equations acquired from elasticity theory. It is worth mentioning that the obtained results proved the validity of numerical analysis of all parameters by ANSYS.
