Abstract
The dynamic damage evolution and the damage-modified constitutive relation for PP/PA polymer blends with different compatibilizers are successfully studied from two approaches: by combining SHPB test with DM-ZWT model and by combining SHPB test with BP neural network. The results consistently show that the damage evolution (including the threshold condition) is dependent on both strain and strain rate.
