Travel Grant to Japan for Planning and Initiating Cooperative Research on Detection of Barely Visible Impact Damage in Composite Laminate Panels

这是亚利桑那大学Tribikram Kundu教授访问东京大学武田伸男教授实验室的旅行补助金。这次访问的目的是启动两个研究所之间的合作研究，利用结合压电和波可视化技术检测复合材料层压板的冲击引起的几乎不可见的冲击损伤。它需要成功完成两项任务：1)预测撞击位置和2)对撞击区域附近的损伤进行评估。首先，在任务1中，需要通过适当的优化技术来预测撞击的大致位置，然后在任务2中，可以使用非接触式激光诱导Lamb波技术来评估撞击区域的损伤。

This is a travel grant for research visits of Professor Tribikram Kundu, University of Arizona, to Professor Nobuo Takedas' laboratory at the University of Tokyo.The purpose of these visits is to initiate a collaborative research between these two institutes on the detection of impact induced barely visible impact damage in composite laminate panels by combined piezoelectric and wave visualization technique. It requires successful completion of two tasks - 1) predicting the impact location and 2) damage assessment near the impact region. First, under task 1 the approximate location of impact needs to be predicted by applying appropriate optimization technique and then under task 2 the damage can be assessed in the impact region by the non-contact laser induced Lamb wave technique.
