Abstract : This report investigates the plane stress capability of the FEARS (Finite Element Adaptive Refinement Solver) program which features both adaptive meshing and a posteriori error bounding. Two benchmark plane stress problems were solved by both the FEARS and NASTRAN (NASA Structural Analysis) programs for comparison. This report presents only the basic computational results. Other reports to follow shortly will motivate the experimental procedures, analyze the results, and provide the conclusion. (Author)
