Helpful Hints and Tips: Case Study on the Influence of Element Mapping and p-Discretization
In this case study, a 3D tie rod under bearing loads was analyzed (CAD courtesy of Digital Engineering). The influences of 1) converting element mapping from isoparametric/quadratic to geometric and/or 2) assigning p-discretization on the peak stress and solver time was documented. Element mapping was considered both on all elements and a subset in the region of interest, and p-discretization was considered on elements outside the region of interest to reduce solver time.

“Aerospace materials scientists and structural engineers now have a new state-of-the-art software product called StressCheck®, which provides efficient and reliable analysis tools for composite bonded aircraft structures. A composites research team from the aeronautics industry, known as the Composites Affordability Initiative (CAI), has just completed an extensive study of current capabilities in the area of failure analysis tools for composite bonded joints. This study led the CAI team to unanimously choose StressCheck® as the software tool to replace as well as radically improve existing industry standard software currently used to size bonded joints.”
