Modeling investigates microcrack behaviors in dual-phase materials under compressive loading, suggesting improved predictions for failure.

The aim is to model the failure behavior of dual-phase microstructures under compressive loading using phase field techniques.
Combined phase field damage and elastic-plastic laws for modeling
Comparison of two approaches for asymmetric damage
Modeling conducted in three dimensions to account for ductility
Incorporation of intrinsic friction into the microcrack process zones
Asymmetric damage significantly affects microcrack patterns and predicted compression at failure
Intrinsic friction enhances predicted macroscopic compression at failure by a factor of 2-3
3D modeling is necessary to accurately represent ductility compared to 2D simulations
A minimum of 8 MPa fracture toughness is necessary for effective material performance under studied conditions.

Huber et al. (2026) studied this question.
