Stress intensity values are generated for a wide range of ratios for crack depth to crack length, crack depth to sheet thickness, hole radius to sheet thickness, and sheet width to hole diameter.
The analytical investigation utilizes the three dimensional virtual crack closure technique and well-structured, completely hexahedral, element meshes. TrueGrid will not run unless your license is authorized to run that version. Otherwise, you do not have permission to download these files. The crack depth to length ratio and depth to thickness ratio can also significantly influence the accuracy of historical finite width solutions and corrections. You may download and install the appropriate version of TrueGrid if your license is under maintenance or you have been instructed to do so by XYZ Scientific Applications, Inc. Early investigations into the validity of this application indicated that this correction procedure produces stress intensity values +/- 30% from new solutions. Many of the available finite width corrections are singled valued and universally applied to all locations along the crack front. The focus of this investigation is to calculate the stress intensity factors of single quarter-elliptical corner cracks emanating from centrally located holes in finite width plates under various loading conditions (remote tension, bending, and pin loading).
