| Description: | Technical Note PURPOSE: The purpose of this Coastal and Hydraulics Engineering Technical Note (CHETN) is to describe the numerical evaluation of the stress intensity factors using the J-integral approach (Rice 1968a, 1968b). The stress intensity factors have been calculated for a semi-infinite plate with an edge crack. This case has a known closed-form solution, and only a 1.25 percent difference between the numerical and closed-form solution was obtained. This CHETN also presents the methodology to perform a detailed three-dimensional (3-D) meshing of any complicated geometry. The meshing approach was used to generate a 3-D mesh of a hydraulic steel structure with multiple cracks. Stress intensity factors for the 3-D problem with multiple cracks are also discussed. This approach is being developed to be used in fracture mechanics analysis of U.S. Army Corps of Engineers structures. |
