This is a CAREER project to investigate hybrid acoustic-infrared NDE imaging mechanisms. The proposed integrated application of infrared (IR) sensing and imaging with pulsed sonic/ultrasonic excitation represents a novel concept. Acoustic wave propagation within materials causes microscopic particle motions, including in the vicinity of defects. An IR camera records the surface temperature distribution above the crack, resulting from the heat flow. Fundamental issues related to this techniques will be studied and optimization of the parameters for the technology will be sought. This will include: mechanisms for heat generation, relative effects of different sound modes, and relative importance of friction and elastic hysteresis, repetitive bond formation and breaking, and other nonlinear effects.The research will contribute to the establishment of a novel NDE technology and provide crossing-cutting impact through practical applications in aerospace, automotive, power and semiconductor industries.Several industrial institutions and two national labs are involved in this research, and an ambitious plan for education including out-reach to minority students is an integral part of this project.

这是一个职业项目，旨在调查混合传染的NDE成像机制。脉冲声音/超声激发的红外感测和成像的综合应用代表了一个新颖的概念。材料中的声波传播导致微观粒子运动，包括缺陷附近。 IR摄像头记录了由于热流而导致的表面温度分布。将研究与此技术相关的基本问题，并将寻求该技术的参数的优化。这将包括：发热的机制，不同声音模式的相对效应以及摩擦和弹性滞后的相对重要性，重复的粘结形成和破坏以及其他非线性效应。该研究将有助于建立一种新型NDE技术，并通过在航空航天，自动企业和半型工业工业中提供交叉效果，并提供交叉的影响研究，以及雄心勃勃的教育计划，包括对少数族裔学生的范围，这是该项目不可或缺的一部分。
