Stress Intensity Factor of Different Position Plates with Eccentric Crack

Abstract:

Aim for calculating stress intensity factor (short for SIF) of different position plates with eccentric crack, and the change tendency between different positions and SIF, the crack model is built by finite element software, and the SIF change tendency line with different width plates is got. It is seen from the von Mises stress cloud chart of ANSYS that the deformation of plate is effected by crack; as the center of crack is gradually close to the edge of plate, SIF is increasing. When the distance between the center and edge of crack is decreasing down to 3/8, SIF is increasing fiercely, that means, the plate at this time has already reached the edge of fracture. If continue loading the stretch, the crack will be apparent on the plate. And the curvature equation is got by index decay adapting.
