- •
HJC model is modified for predicting cratering and scabbing of concrete slab under projectile impact.
- •
Modifications are validated by comparing with the available test data.
- •
DIF for tension and fracture strain are important for scabbing simulation.
- •
DIF for tension and the ratio of current to compressive meridians are crucial for cratering simulation.
