In this paper an effort is made to find stress intensity factor near the crack tip.Cracks in plates with different configurations often occurs in both modern and classical aerospace, mechanical and civil engineering structure. The understanding of effect of loading mode and crack configuration on load bearing capacity of such plate is very important in designing of structure and in damage tolerance analysis. A number of Analytical, Numerical, and Experimental techniques are available for stress analysis to determine the stress intensity factor near crack tip under different loading modes in an infinite /finite plate made up of different materials. In this paper stress intensity factors are determined for four key geometric configurations. These configurations were developed by using finite element method packages. Two dimensional finite plates under uniaxial loading with either: edge crack, both edge cracks, crack approaching circular hole, crack approaching triangular hole are considered for investigation.
