Problem statement

Geometry: NAFEMS R0026 contains ten material non-linearity benchmarks. Keep this as a suite placeholder until licensed geometry and target data are available.
Material: Constitutive or analytical definition: Published benchmark suite.
Boundary conditions: Required solver capability: material_nonlinearity. Use the loading/path control stated in the setup and preserve the complete response history.
Measured quantity: No benchmark values are copied into this corpus. Record only IDs and solver-owned pass/fail results after legal review.
