Thermo-Mechanical Fatigue
- Thermo-Mechanical Fatigue
Thermo-mechanical fatigue (short TMF) is the overlay of a cyclical mechnical loading, that leads to fatigue of a material, with a cyclical thermal loading. Thermo-mechnical fatigue is an important point that needs to be considered, when constructing turbine engines or gas turbines.
Cyclical mechanical loading applied to a material leads to material fatigue.
When a cyclical thermal load is applied to a material it will fail by thermal fatigue due to induced thermal stresses.
