Thermo-Mechanical Fatigue - White Paper
Thermo-mechanical fatigue (TMF) is an engineering challenge across the aviation, power, transportation and electronics industries. In the transportation industry, components like in-cylinder exhaust manifolds and turbochargers see high temperature and mechanical load variations that can lead to thermo-mechanical fatigue. TMF occurs in electronic components because of the increasing power density of electronic packages, plus their increased usage in harsh environments. ANSYS’ state-of-the-art nonlinear material models help to simulate creep and fatigue of metal alloys with high accuracy, eliminating time-consuming and costly physical testing. Once the material is characterized, ANSYS Mechanical and CFD solutions can study what the component experiences as it goes through the duty cycle.
