A useful test set should include zero-energy mode checks, membrane and bending patch tests, isotropy checks for triangular elements, convergence curves, and global error measures such as S-norm. The test problems should also vary the shell's Gaussian curvature, thickness, layer behavior, asymptotic behavior, and element mesh shape. This exposes whether the element is only tuned for a narrow problem class or is robust enough for design analysis. ## Benchmark Dimensions - Basic element checks: zero-energy modes, patch tests, and element isotropy. - Geometry: positive, zero, and negative Gaussian curvature. - Asymptotic behavior: bending-dominated, membrane-dominated, and mixed-dominated shell problems. - Error view: global error norms and field distributions, not only one output point. - Mesh sensitivity: element distortion, anisotropic meshes, and orientation effects. ## Connections - [[Scordelis-Lo Shell Benchmark]] is one important benchmark in this family. - [[Shell Locking Phenomenon]] is a primary failure mode benchmark tests should reveal. - [[Uniform Optimal Convergence]] is the performance target. - [[MITC4 Shell Element]] uses benchmark evidence to support its practical reliability. ## Sources - [[On-the-Finite-Element-Analysis-of-Shell-Structures]]
