Finite Element Analysis of Stress Concentration at Rounded Crack Tip with Different Physical Parameters

Abstract:

This paper investigates the effect of physical parameters of a rounded crack on the stress concentration near crack tip. The depth and radius at the crack tip are the two physical parameters concerned in this study. The finite element method was used to evaluate the stress value at the crack tip for a silicon chip with a tiny crack under tensile stress. Element type, shape and physical parameters of crack were varied to study their effect on the stress concentration near the crack. The simulation results were compared with the theoretical value, and the better physical parameters as well as the element type, element shape were discussed.
