Abstract Intermittent mechanical loads combined with high temperatures appear during the operation of turbines in jet engines or power plants, which can lead to high-temperature fatigue thermomechanical fatigue. Since assessment properties is a complex and time-consuming process, it essential develop validated material models that are capable predicting behavior, thus allowing extrapolation exp...

This work presents an open source, dislocation density based crystal plasticity modeling framework, ρ-CP. A Kocks-type thermally activated flow is used for accounting the temperature and strain rate effects on crystallographic shearing rate. Slip system-level mobile immobile densities, as well slip backstress, are internal state variables representing substructure evolution during plastic defor...

Phase field models for ductile fracture have gained significant attention in the last two decades due to their ability implicitly tracking nucleation and propagation of cracks. However, most crack phase formulations elastoplastic solids focus only on effects plastic deformation , do not consider different multi-axial stress states that may arise practical designs. In this work, a thermodynamica...

The increasing application of aluminum alloy, in combination with the growth complexity components, provides new challenges for numerical modeling sheet materials. material elastic–plasticity constitutive model is most important factor affecting accuracy finite element simulation. mixed hardening can more accurately represent real characteristics plastic deformation process, and property-relate...
