Thermo-mechanical FEA — coupled thermal-structural analysis, sequential (one-way) vs. fully coupled formulation, thermal strain ε_th = α×ΔT, temperature-dependent material properties, creep (Norton power law), fatigue life from thermal cycling (Coffin-Manson), mesh requirements for thermal gradients, transient heat conduction FEA, contact thermal resistance, and ANSYS/Abaqus workflow for turbine blades, engine components, and electronics.
