Abstract

In this paper, a series of experiments were conducted aluminum plates to investigate the large plastic deformation of single, double, and triple-layered plates under repeated uniform loading up to five times. In order to perform experiments, plates were mounted onto a ballistic pendulum. Generally, the tested plates represented large plastic deformation of dome-like shape along with thinning or tearing occurring at the boundary due to the uniform impulsive loading. The experimental results showed that the maximum permanent delfection of single- and multi-layered plates increases by the increase of mass charge and number of blasts. Furthermore, the progressive deflection was decreased exponentially because the test plate material undergoes work hardening after each blast load. The results also indicated that triple-layered plates made of similar materials may have a better blast performance compared to double-layered at the first low-impulse blast but their resistance decreases as the number of blast increases. However, this trend was not observed for high-impulse blasts and multi-layered plates have a different behavior.
