Lifetime calculation for turbine housing of turbocharger under thermo-mechanical loading: damage operator approach
Original language description
The paper presents an application of a damage operator based lifetime calculation for the turbine housing of the turbocharger under thermo-mechanical loading. Results from the transient thermal FEA are used as the main load parameter in the structural FEA. Two approaches are applied in order to match different requirements. The first is based on the elastoplastic analysis with non-linear kinematic hardening. A viscoplastic approximation, based on the strain controlled Maxwell model, is the part of post-processing step, where the Prandtl type operators are used. The second approach is based on a viscoplastic structural analysis, where the stabilized state of the structure subjected to cyclic loading is obtained by the Direct Cyclic procedure. In both cases, the damage operator is used for the continuous fatigue damage calculation. Creep damage is separated and calculated with the well-known time-fraction rule.
