Webb1 aug. 1991 · Coupling between mechanical and thermodynamic processes can be significant in solid media when material inelasticity occurs. Significant mechanical energy may be converted into heat via hysteretic loss, and this coupling may be significant even under quasi-static conditions. Webb9 sep. 2007 · One- and two-way thermomechanically coupled micromechanical analyses of multiphase composites are presented. In the first type of thermomechanical coupling, a constant temperature that affects the mechanical field only is prescribed at any point of the composite’s constituents.

Thermomechanical coupling in cyclic phase transition of …

Webb9 nov. 2024 · A direct-coupling thermomechanical analysis is performed using a three-dimensional (3D) RPV finite element model. A 3D finite element submodel (consisting of the highiest stress concentration area in the RPV) and an assumed crack are then used to perform fracture mechanics analysis. WebbThermomechanical feedback represents a first-order multiphysics coupling for geodynamic processes. For instance, thermomechanical coupling plays a major role in initiating and regulating convection currents at the scale of the Earth’s mantle (Pekeris 1935; McKenzie et al. 1974; Parsons & McKenzie 1978 ). playtime with al toys

Large-scale connecting segments can provide reasonable load transition in hybrid girders, and have been broadly used in long-span cable-stayed bridges. … Webb6 jan. 2024 · In the thermo-mechanical coupled analysis problem, there may exist uncertain parameters related to the Young’s module, Poison’s ratio, thermal expansion coefficient, temperature field, and applied loadings. Thus, the computational burden becomes heavier for problem with a relatively large number of uncertain parameters.
