# Thermal Stress

## Stress when restricting thermal expansion

Sponsored Links

Tensile or compressive stress is a result of restricted thermal expansion.

Thermal stress can be calculated as

*σ = E ε *

* = E α dt (1)*

*where *

*σ = stress due to temperature expansion (N/m ^{2}, Pa)*

* E =Young's Modulus (N/m ^{2})*

*ε = strain*

*α = temperature expansion coefficient (m/m ^{o}C)*

*dt = temperature difference ( ^{o}C)*
