sci.ceramic-thermal-shock-resistance Calculator
Calculates thermal shock resistance parameter R = σ_f × (1−ν)/(E × α) for ceramics and estimates critical temperature drop for survival. Al₂O₃: R ≈ 38 °C — even modest thermal gradients cause fracture; SiC has R ≈ 150 °C due to its high thermal conductivity.
Inputs
Sigma Mpa
Reference formula or conversion factor shown for context.
K W Mk
How easily heat flows through the material (W/m·K). Metals are high; insulation materials are very low.
E Gpa
Material stiffness (GPa). Stress divided by strain in the elastic range. Steel: 200 GPa. Aluminium: 70 GPa. Rubber: 0.01–0.1 GPa.
Alpha Per K
Reference formula or conversion factor shown for context.
Nu Poisson
Reference formula or conversion factor shown for context.
Results
thermal shock resistance R (°C)
Opposition to current flow (Ω). Ohm's Law: V = IR. Lower resistance means more current for the same voltage.
