Nettet9. apr. 2024 · L – L0 = L0α ΔT, where α is the coefficient of linear expansion of the material. In that case, L = L0 (1 + α ΔT) Hence, thermal stress = F/A = Y (L - L0) / L0 where Y is Young’s modulus of the given material. This can be simplified into Y (α ΔT) / L0 This is considered as the thermal stress formula. NettetFracture mechanics is a methodology that is used to predict and diagnose failure of a part with an existing crack or flaw. The presence of a crack in a part magnifies the stress in the vicinity of the crack and may result in failure prior to that predicted using traditional strength-of-materials methods .
