Crack Initiation, Propagation and Stress Intensity Factor of Rectangular Plate with Circular Hole by FEA Approach

Abstract

The study of crack behavior in a plate with hole is a considerable importance in the design to avoid the failure. This situation has a look at offers with investigation of stress intensity factor, von-mises stress (ϭ von-mises) at the finite center cracked plate subjected to uniform tensile loading depends at the assumptions of linear elastic fracture mechanics (LEFM) and plane strain problem. The stress intensity factors mode I (KI) are numerically calculated by finite element solution using ANSYS (ver. 15) software and theoretically using standard equations for different crack lengths and plate dimensions. Commonly, the consequences show that there are not any essential differences among the two techniques. However, the difference between the two methods occur if we take the plate length parameter in considerate. Furthermore, ϭ von-mises at crack tip region on the crack tip stresses are studied.
