Abstract Scope |
This study investigates the orientation dependence of intragranular void evolution and failure in aluminum alloy using a coupled phase-field damage (PFD) and crystal plasticity (CP) model within a finite element framework. It addresses the heterogeneous and anisotropic nature of damage evolution at the grain scale in engineering metal alloys, highlighting the influence of crystal orientation on stress and strain localization, void nucleation, and growth. By implementing a dislocation dynamic-based constitutive model for CP and an anisotropic PFD method the study provides insights into void shape changes, elongation, and coalescence under varying stress triaxiality levels. The findings, validated against experimental data, reveal a strong correlation between crystal orientations and void growth, offering a predictive tool for failure in crystalline materials and supporting data generation for machine learning models.
