Thermal fatigue is a fatigue failure with macroscopic cracks resulting from cyclic thermal stresses and strains due to temperature changes, spatial temperature gradients, and high temperatures under constrained thermal deformation. Thermal fatigue may occur without mechanical loads.

Thermal fatigue is a specific type of fatigue failure mechanism that is induced by cyclic stresses (thermal expansion and contraction) from repetitive fluctuations in the temperature (heating and cooling) of equipment.
May 27, 2024 · Understanding Thermal Fatigue: Causes and Prevention. Thermal fatigue, a phenomenon commonly encountered in materials exposed to cyclic temperature changes, is a critical concern in various industries, particularly those involving high-temperature operations.
Thermal fatigue refers to the progressive and localized structural damage that occurs in materials due to cyclic thermal loading. This phenomenon is particularly relevant when materials experience repeated temperature fluctuations, causing them to expand and contract, which can lead to the formation of cracks and eventual failure.
Jul 19, 2024 · What Does Thermal Fatigue Mean? Thermal fatigue refers to a progressive degradation of a material due to cyclic fluctuations in temperature. Thermal fatigue primarily afflicts metals because they are highly conductive and inherently receptive to temperature changes.
Thermal fatigue is a dramatically severe form of fatigue. Whereas normal high-cycle fatigue occurs at stresses comfortably in the elastic range (i.e. usually well below the yield point) thermal fatigue is driven by thermal strains that force deformation well into the plastic flow regime.
Thermal fatigue arises from repeated heating and cooling cycles, causing thermal expansion and contraction within a material. This can induce significant stresses, especially in components with constrained geometries or those made of materials with differing thermal expansion coefficients.
