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.
