Abstract

Abstract: It is being observed that the mesh density plays an important role while determining the accuracy of the results, Thus in this paper the mesh density is increased for the plate. The mesh density effect will be on stress intensity factor or stress gradient, the degree of freedom per node will be different, and the micro surface with respect to node will be different. There are tools where the auto meshing is done but here the meshing increasing effect is done manually by various researchers, as the geometrical configurations are complicated. There are variety of joints that are mostly used in industries, different materials are joined widely, thus it is an interesting area to understand cracks with meshing effects, due to excessive loading or corrosion cracks may happen and thus in the earlier research there were different parameters that were tested in the crack propagation simulation analysis. In this paper, through Fortran programming, the rectangular crack tip is analyzed and tecplot software, integrated with fortran output file plots the graphs of the effective stress, volumetric change and hydrostatic stress which are compared for the incompressible material only. The meshing is being increased from 22x60 to 22x64 and the effects are being analyzed. The stress intensity factor is 0 to 1.5 in input file.
