Thermal Stress Formula
Formula
σ = E × α × ΔT
Where:
- • σ = thermal stress (Pa)
- • E = Young's modulus (Pa)
- • α = coefficient of thermal expansion (1/K)
- • ΔT = temperature change (K)
Thermal Strain
ε = α × ΔT
Strain from thermal expansion
Note
This formula applies when expansion is constrained. For unconstrained expansion, stress is zero.
