Equation Of State And Strength Properties Of Selected -

Selected materials, such as metals (e.g., Al-6061) or ceramics (e.g., Silicon Carbide), require distinct modeling approaches. For metals, the Johnson-Cook or Steinburg-Guinan models are often paired with a Mie-Grüneisen EOS. These models account for "work hardening" and "thermal softening," where the material gets harder as it deforms but softer as it heats up. For brittle materials like ceramics, strength models must also include "damage variables" to account for micro-cracking, which causes the material’s strength to vanish rapidly upon failure.

Accurate modeling of shock waves requires a coupled approach, using both the EOS (for pressure) and a strength model (for resistance to shear). Selected materials, such as metals (e
