【 摘 要 】

The correlations between the structures, fracture behavior and dynamic shear property were investigated for 7050 to 7N01 layer of 7N01/7A01/7050 multilayer plate with different thickness ratio fabricated by hot rolling bonding. is The results showed that when thickness ratio of 7050 to 7N01 layer was 1 and 7050 layer was backplane, the absorbed energy of the multilayer plate was 39% higher than that of 7050 alloy. The excellent energy absorbing ability of 7N01/7A01/7050 multilayer plate is attributed to the blunted cracks in 7A01 interlayer, the enhanced 7050 layer by decreasing of secondary cracks and the delaying dynamic failure of 7050 layer.
