# Shell Element Benchmark Testing
|
|
|
|
## Definition
|
|
|
|
Shell element benchmark testing is the structured evaluation of shell finite elements across basic element checks, convergence measures, shell geometries, asymptotic behavior classes, and mesh patterns.
|
|
|
|
## How It Works
|
|
|
|
The source argues that shell element performance should not be judged only from a displacement at one point. 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.
