This CAREER project addresses the complex problem of modeling, analysis, and experimental investigation of nonlinear characteristic related to smart materials, such as piezo-ceramic composites, and investigates their application in vibro-acoustic energy conduction transduction, dissipation and excitation. This research is vital for meeting critical needs in applications such a structural noise and vibration control, non-destructive testing and evaluation, health monitoring of structures and machinery, music and micro-electro-mechanical systems. The education plan is integrated fully with the proposed research topic. It included outreach activities involving inner city youth through the medium of music via a non profit program called Music Education Reaching Instrumental Talent (MERIT). In this program, the PI plans to incorporate a sequence of instructions on `Science and Engineering in Music.` In addition, he plans to augment the laboratory experience in UIC Minority Engineering Recruitment and Retention Program with `Science and Engineering of Musical Instruments,` in which students first study traditional musical instruments, and then design and develop their own musical instrument. The project will result in a better understanding of vibro- acoustic energy transmission, and engineering concepts via musical acoustics.

该项目致力于解决与智能材料(如压电陶瓷复合材料)相关的非线性特性的建模、分析和实验研究的复杂问题，并研究其在振声能量传导传递、耗散和激励方面的应用。这项研究对于满足结构噪声和振动控制、无损检测和评估、结构和机械的健康监测、音乐和微电子机械系统等应用的关键需求至关重要。教育计划与拟议的研究课题完全结合在一起。它包括通过一项名为音乐教育达到器乐天赋(MERIT)的非营利性方案，让市中心的青年通过音乐媒介开展的外联活动。在这个项目中，PI计划纳入一系列关于“音乐科学和工程”的指导。此外，他还计划在UIC少数民族工程招生和保留计划中增加实验室经验，增加“乐器科学和工程”，即学生首先学习传统乐器，然后设计和开发自己的乐器。该项目将通过音乐声学更好地理解振动-声学能量传输和工程概念。
