Asay window for probing the microspall of materials
-
摘要: 微层裂是冲击波物理领域的重要基础问题，在工程上具有重要应用价值。近年来用于诊断样品多层层裂的传统Asay窗技术被用于诊断微层裂，但对其诊断能力和信号特征认识仍存在严重不足。为此，通过波系分析，揭示出在薄飞片击靶的微层裂实验中样品破碎存在1个“痂片”特征区、2个微层裂特征区以及1个“残体”特征区。实验表明，在样品窗口间隙合适的条件下，Asay窗不仅能够有效区分这些不同特征分区，而且能够灵敏探测样品表面发射的高速微喷粒子，从而实现对样品连续破碎过程的精密诊断。Abstract: Microspall is an essential problem in both theoretical investigation and engineering application in shock physics. The Asay window, originally developed to diagnose the multi-spall behavior of material, was recently employed to probe the microspall, but its ability for probing the problem calls for further demonstration, and the corresponding signal also needs further explanation. In this paper, wave propagation analysis indicates that the sample bearing microspall can be separated into several different characteristic regions, the experiments performed demonstrate that the Asay window can sensitively distinguish these regions as far as a reasonable experimental configuration is set up, and even the features of the micro jet particles can be detected. So the technique was proved of great value for dynamic fragmentation studies.
