Expansion stress formula

Question

Accepted Answer

Expansion stress formula calculates the stress caused by thermal expansion or contraction.

Expansion stress formula is given by: ΔL/L = αΔT, where ΔL is the change in length, L is the original length, α is the coefficient of thermal expansion, and ΔT is the change in temperature.
The formula can be used to calculate the stress caused by thermal expansion or contraction in piping systems.
The formula assumes that the material is homogeneous and isotropic, and that the temperature change is uniform throughout the material.
The formula can be modified to include other factors such as the modulus of elasticity and Poisson's ratio for more accurate results.
