Validation Summary
Automated solver validation report with current pass/fail status and references. Kept separate from the industrial benchmark catalog.
Validation Cases
Benchmarks and validation cases sit at the same strategic level as videos: not because they drive more traffic today, but because they become durable technical assets.
One well-documented benchmark can remain useful for years through citations, technical searches, GitHub, LinkedIn, and direct comparison workflows. For that reason, this section is organized as one main landing page with categories inside it.
Solver Validation
FEM Fundamentals
Cantilever Beam
Baseline structural case for checking simple elastic bending behavior and reference displacement fields.
Cook Membrane
Standard bending-dominated membrane test for displacement accuracy and locking sensitivity.
Patch Test
Consistency check for basic element behavior under constant-strain states.
Contact & Nonlinear Mechanics
Contact Block
Reference contact case for normal enforcement, pressure transfer, and basic nonlinear convergence behavior.
Hertz Contact
Classical contact-pressure benchmark with an analytical background for comparison.
Penalty Contact
Useful for studying enforcement stiffness, penetration control, and robustness across contact settings.
Metal Forming
Cold Upsetting (Coulomb Friction)
Open-die upsetting benchmark for validating the Coulomb contact law, pressure-dependent traction, and load evolution.
Hot Upsetting (Shear Friction)
Open-die upsetting benchmark for validating the shear-friction law, sticking-limit behavior, and bulk-forming contact response.
Ring Compression
Planned calibration case for friction sensitivity and barreling/contact trends.
Backward Extrusion
Multi-stage cold forming reference case tied to the Torx nut study and suitable for contact-heavy validation.
Closed Die Forging
Impression-die forging benchmark intended for validating filling, flash generation, and contact robustness.
Direct Extrusion
Forward extrusion case for checking flow through the die, pressure levels, and steady-state shape prediction.
Explicit Dynamics
Cantilever Beam
Transient explicit beam response with imposed tip deformation, rigid contact, and free vibration after release.
2D/3D Tensile Test
Explicit tensile benchmark in 2D and 3D with a 1 m/s imposed speed, manual mass scaling through density, and generic aluminum plasticity.
Explicit Compression
Planned benchmark for impact-free but fully transient compression under explicit integration.
OpenRadioss Comparison
Planned cross-code comparison slot for explicit dynamics cases and solver-to-solver response tracking.
Impact Cases
Reserved category entry for future high-rate and collision-driven benchmark problems.
Thermo-Mechanical
Hot Forging
Planned coupled benchmark for temperature-dependent flow, die contact, and deformation evolution.
Thermal Coupling Cases
Reserved group for coupled thermal-mechanical validation with heat transfer and transient temperature fields.
