CAREER: Determining Time and Temperature-Dependent Material Properties for Small Components: Integrated Education and Research

电子和微电子机械设备(MEMS)规模的不断缩小表明，在材料的长度-尺度效应不容忽视的情况下，需要材料的性能。随着工业对聚合物和新型焊料合金的研究，温度依赖性和蠕变行为是首要关注的问题。该计划将在从亚微观到宏观的长度尺度上执行新颖的速率和温度相关实验，并进行详细的机械建模，以建立微观测试和材料特性之间的联系。这一综合研究和教育计划的核心是开发新的测试程序，这些程序将被实施到现有的纳米压痕设施中。这些微弯曲和微扭转测试将在现有的高级设计和加速硕士学位课程中开发。这些项目将使学生面临尖端产品开发和研究的挑战，并为他们提供本科课程中通常找不到的大量技能。

The ever-decreasing scale of electronic and micro-electro-mechanical devices(MEMS) indicate that material properties are needed in regimes which materiallength-scale effects cannot be ignored. As industry looks towards polymersand new soldering alloys, temperature-dependence and creep behavior is ofprimary concern. This program will perform novel rate- andtemperate-dependent experiments on length-scales ranging from the sub-micronto macroscopic, and detailed mechanical modeling to establish the link betweenmicro-tests and material properties. At the core of this integrated researchand education plan is the development of novel test procedures that will beimplemented into an existing nano-indentation facility. These micro-bend andmicro-torsion tests will be developed within existing senior design andaccelerated master's degree programs. These projects will expose students tothe challenges of cutting-edge product development and research, and providethem with considerable technical skills not typically found in anundergraduate program.
