Thermal Stresses

Stress due to restricting thermal expansion

Tensile or compressive stress may be caused by restricting thermal expansion. Thermal stress can be calculated as

σ = E ε 

   = E α dt    (1)

where

σ = stress due to temperature expansion (N/m2, Pa)

E =Youngs Modulus (N/m2)

ε = strain

α = temperature expansion coefficient (m/moC)

dt = temperature differance (oC)
