摘要：
A shock tube facility is used for the airblast loading of prefabricated aluminum plates with different hole shapes to study the damage effect of airblast loading on the plate structures after fragment perforation. The dynamic response of fixed supported aluminum plates under airblast loading is analyzed by using the three-dimensional digital image correlation (3D-DIC).The influences of different hole shapes on the stiffness, failure mode and bearing capacity of target plate are analyzed based on 3D-DIC results. The results show that the target plate with circular holes has the maximum stiffness and the ultimate bearing capacity, and the target plate with diamond-shaped holes has the lowest ultimate bearing capacity. The influence of hole shape on tear failure is mainly reflected in the distribution of corner point of hole on target plate. The experimental results have certain reference value for the anti-explosion design of fixed support plate structures. © 2021, Editorial Board of Acta Armamentarii. All right reserved.
