Title: Research on the Mechanism of Ice Damage of Ice Fragments under Near-field Underwater Explosion

Abstract: In polar region, mineral resources are extremely rich, and their military value and shipping value are being paid more and more attention by all countries. However, the risk of war preparation resource transportation by navigation in ice areas is great, which makes the research on near-field underwater explosion and ice breaking possesses high academic value and practical significance. In view of the mesoscopic damage of ice under near-field underwater explosion, the numerical analysis models of shockwave-ice and bubble-ice coupling are established, and the mesoscopic evolution process of ice section damage under near-field underwater explosion is described and analyzed. Based on the theory of one-dimensional stress wave propagation, to analyze the stratification phenomenon of ice layer, the law and mechanism of ice layer damage and crack propagation under the near-field underwater explosive load are obtained. And, in view of the macroscopic damage of ice layer under near-field underwater explosion, the phenomenon of bubble jet penetrating through the thin ice layer and invading the thick ice layer by two kind of typical bubble jets with different motion forms are obtained respectively. Moreover, the sensitivity of the damage effect of bubble jet to the detonation distance of ice layer under the load of bubble jet is obtained.

报告题目:近场水下爆炸下冰层损伤破坏机理及碎冰散射特性分析

摘要:在极地地区,矿产资源极其丰富,且其军事价值和航运价值正不断地被各国重视,但冰区航行进行战备资源运输危险较大,使得近场水下爆炸破冰的研究具有很高的学术价值以及现实意义。针对近场水下爆炸作用下冰层的细观损伤,建立了冲击波-冰层及气泡-冰层耦合作用的数值分析模型,对近场水下爆炸下的冰层断面损伤细观的演变过程进行了详细的描述分析。基于一维应力波传播理论,分析了冰层的层裂现象,推导得到了近场水下爆炸载荷作用下的冰层损伤和裂纹扩展规律和机理。针对近场水下爆炸作用下冰层的宏观毁伤问题,分别研究气泡射流贯穿薄冰层,以及两种典型不同运动形态的气泡射流侵入厚冰层的现象,同时针对冰层在气泡射流载荷作用下的毁伤效应对爆距的敏感性进行了研究。
