چکیده مقاله:

In the prior studies, the analytical methods using by partial differential equations were utilized as the best methods in order to investigate the fracture mechanics. Despite problems such as geometric complexity, complex material behavior, boundary conditions, and various loads, it was difficult to come up with an accurate solution. Hence, the numerical methods are used instead of the analytical methods to examine cracked structures. In research, the stress and the strain fields of 2-Dimentional are modeled for DLSP cracked using by Abaqus software. As a results, environmental stress contours, around the crack tip have negative values. While the Mississippi fan tension contours, have positive values everywhere
