MacNeal-Harder Test This is a twisted cantilever beam solved with solid and shell elements. A model is made with each element's type
to investigate the effect of distorted elements with a high aspect ratio.
MacNeal-Harder Test This is a curved cantilever beam solved with solid and shell elements. A model is made with each element's type to
investigate the effect of distorted elements with a high aspect ratio.
MacNeal-Harder Test This is a straight cantilever beam solved with solid and shell elements. Three models (rectangular, parallelogram,
trapezoidal) are made with each element's type to investigate the effect of distorted elements with a high
aspect ratio.
MacNeal-Harder Test The Scordelis-Lo Roof is a classical benchmark problem for shell elements. Analytical and experimental investigations
were initially performed by Scordelis and Lo.
Raasch Challenge Raasch challenge is a curved strip hook problem with a tip in-plane shear load, posed in 1990 by Ingo Raasch of BMW
in Germany. The problem poses a significant challenge to shell elements because of the inherent coupling between
three modes of deformation: bending, extension, and twist. OptiStruct is benchmarked against the Raasch challenge to assure its shell elements performance on Linear Static Analysis.
