| Abstract: | Debonding has important influence on the capability of ceramic composite armors against multi-hit.Based on published ballistic experiments,the debonding problems of ceramic/aluminum composite armors under the impact of 7.62 mm armor piercing projectile(APP) was numerically investigated by LS-DYNA,in which the model with adhesive layer was used.The contact stress failure criterion was compared with the adhesive layer stain failure criterion,and the debonding mechanism of polyurethane layer was studied.The re... |
