← Back to Domain-Specific Abstractions by Domain

4 domain-specific abstractions whose origin domain is Materials Science.

• Acoustic emission — Transient elastic waves released within a solid by rapid irreversible changes such as crack growth, plastic deformation, or phase transformation.
• Ball-on-ring test — Estimate the biaxial flexural strength of a brittle disk by loading its central region against annular support so the critical tensile field lies away from edge flaws, with stress inferred through a declared mechanics model.
• Ductility — A material’s capacity to undergo substantial plastic deformation in tension before fracturing.
• Lamellar structure — A material microstructure made of fine alternating plate-like layers of distinct phases, commonly produced by coupled growth during eutectic or eutectoid transformations.
