StressCheck Tutorial: Performing h-Discretization to Refine Manually Generated Meshes
Abstract: If convergence is not achieved for a full p-extension on a manually-generated mesh of hexahedra/pentahedra (3D) or quads/tris (Planar), h-Discretization is the most efficient way to refine the mesh. Manually-generated meshes can be refined uniformly for elements, or geometrically graded from selected geometric boundaries, element faces (3D) or element edges (Planar).

“Accurate and reliable stresses and Stress Intensity Factors are required for determination of static and residual strength and for crack growth analyses in analysis tools such as AFGROW. For some geometries, industry solutions are either insufficient or nonexistent. The geometry, applied forces, and crack shapes and dimensions must be modeled reasonably well to obtain useful engineering data. The p-version finite element software StressCheck® (ESRD, Inc., St. Louis, Missouri, USA) is used to demonstrate how accurate finite element solutions can lead to good quality engineering analysis.”
