    摘要:

    目前研究人员获得了陶瓷/金属、陶瓷/纤维等复合结构抗弹性能受周向约束影响的大量成果,但尚未针对泡沫铝陶瓷复合结构受周向约束影响特性开展相应研究工作.本文基于试验与数值仿真手段,开展了周向约束对泡沫铝陶瓷复合结构抗弹性能的影响研究,结果表明:周向约束是泡沫铝陶瓷复合结构损伤破坏模式的重要影响因素,对陶瓷板、泡沫板施加周向约束能限制陶瓷板裂纹扩展,增加抗侵彻阻力,有利于增加复合结构的吸能作用,提高复合结构抗弹性能.

    Abstract:

    Many results has been obtained regarding anti-penetration performance of ceramic/metal and ceramic/fiber composite structure influenced by circumferential restriction, but relevant research of ceramic composite structure containing aluminum foam is still absent. This paper studies effects of circumferential restriction for anti-penetration performance of ceramic composite structure containing aluminum foam, based on experiments and numerical simulations. The results show that circumferential restriction is the key mechanism of damage characteristics of ceramic composite structure containing aluminum foam, ascircumferential restriction of ceramic and aluminum foam plate could limit crack propagation of ceramic plate and aluminum foam plate and increase resistance, thus enhancing energy consumption of composite structure, and improving the anti-penetration performance.
