| Abstract | ||
| ABSTRACT:- Forming dies contain one form or another of stress concentrators due to shape corners, holes and notches that contribute to die failure. Avoiding and minimizing the effects of such concentrators is vital in die design and fabrication. The purpose of this paper is to study the effect of multiple concentrators along one axis in an infinite plate subject to tension loading. The study was carried out using Finite Element Method. The present results indicated that stress concentration in the notch has occurred at or near the normal to loading direction. Results concerning multiple stresses concentration factors increases or decreases depending on: the Notch angle, Notch depth, and Notch root radius. | ||
