Brief description of the evaluation of the resistance to fatigue thermomechanical of at least one material

摘要

The method involves calculating a temporal temperature evolution (1) of a part e.g. exhaust line part, of a base material for a critical zone on the part of material. A temporal evolution of a value of uniaxial mechanical deformation is calculated for the critical zone, where the value is compared to a parameter of thermo mechanical stress. The temporal evolution of the value of uniaxial mechanical deformation is applied for determination of thermal cycles for evaluation of a specimen of the part of the material. A set of nodes is selected in the critical zone.
