A 3D brittle fracture model with effect of microstructure, strain gradient and strain rate

Puntos clave

• Brittle fracture occurrences are influenced by strain gradient and rate, affecting material performance.
• The model successfully integrates microstructure variability, enhancing the understanding of fracture behavior in materials.
• Employing a 3D framework allows for comprehensive analysis and simulation of fracture processes under varied conditions.
• These findings may enable improved material designs by addressing how microstructure impacts fracture mechanisms.
