  - OS-V: 0700 Twisted Cantilever Beam (Implicit Results)
    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.
  - OS-V: 0710 Curved Cantilever Beam
    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.
  - OS-V: 0720 Straight Cantilever Beam
    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.
  - OS-V: 0730 Scordelis-Lo Roof
    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.
  - OS-V: 0740 Curved Strip Hook
    Raasch ChallengeThe 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.
  - OS-V: 0750 Radial Stretching of a Cylinder
    Illustrates the use of asymmetrical elements (CTAXI) under uniform radial displacement in OptiStruct.
  - OS-V: 0760 MacNeal-Harder Solid Patch Test
    MacNeal-Harder TestThe patch test is a classical benchmark problem for the element. If it produces correct results for the test, the result for any problem solved with the element will converge toward the correct solution. The intended purpose of the proposed problem set is to ascertain the accuracy of finite element in various applications.
