Abstract
En 中文
• Coupled SHPB tests and mesoscale models reveal CAC compression–shear behavior. • RHT model outperforms HJC and K&C in capturing CAC compression–shear coupling. • Simulations quantify inaccessible dynamic stress-strain and energy dissipation. • Crack morphology transitions from axial V-shape to oblique shear localization. • A rate-dependent Drucker-Prager criterion accurately describes CAC failure.
