| Abstract | ||
| The objective of this paper is to study the effect of loading system and direction on stress concentration around a square hole in an infinite plate using (FEM) . The study involves the effect of uniaxial and biaxial loading on stress concentration factor ( Kt ) in an infinite steel plate that contains a central square hole(6)mm a side , beside the type of loading (tension and compression (, the effect on stress concentration factor is also considered. Results have indicated that under uniaxial tensile loading , stress concentration occurs at the four corners of the hole, however under uniaxial compression loading, results were similar excepts for the sing of stress in biaxial loading (tension)results showed that (Kt) was higher than in uniaxial loading and when biaxial loading(tension and compression( stress concentration is still higher than that due to uniaxial loading . | ||
