chatmaterials Mechanics Analysis
Use this skill for mechanics-oriented post-processing rather than generic workflow setup.
When to use
- fit an energy-volume curve
- estimate an equilibrium volume and bulk modulus
- judge whether the EOS fit quality looks exact-like, good-fit-like, or noisy
- summarize an elastic tensor
- screen elastic stability heuristics, anisotropy, hardness, and ductility descriptors
- rank multiple mechanics candidates with a compact bulk-plus-stability heuristic
- interpret a stress tensor or stress state
- write a compact mechanics-analysis report from existing calculations

Guardrails
- Treat the simple EOS fit as a compact estimate, not a full published EOS treatment.
- State whether the elastic stability criteria used are heuristic or rigorous.
- Distinguish mean stress from a sign-convention-specific pressure.
