超高应变率拉伸破碎铝的粒子尺寸测量
|
摘要
材料在超高应变率下发生的动态拉伸破碎是冲击波物理领域的一个重要内容,受诊断技术限制,粒子尺寸直接测量的数据非常有限。基于脉冲激光同轴全息技术,建立了一套材料超高应变率破坏状态和破碎粒子诊断的高精度联合测量系统,利用该系统,成功开展了107~108/s超高应变率范围内铝的动态破碎粒子在位测量,获得了粒子尺寸分布数据。
Dynamic fragmentation of material under superhigh strain rate is a topic of increasing interest in shock physics.However,due to diagnosis technique limits,high-quality experimental data of particle size of the fragmentation are quite sparse.Recently,based on in-line holography,we have explored a technique to diagnose the dynamic fragmentation process and measure particle size of fragmentation.Using this diagnosis system,an experiment of laser-shock-melted aluminum has been successfully performed,in-situ data of fragment particles have been obtained in melted aluminum for strain rate ranging from 107~108/s,which gives confidence to our measurement technique for dynamic fragments with high precision.
