This project focuses on enhancing undergraduate materials engineering education in the area of the mechanical behavior of structural materials. An innovative methodology is being presented, in which students perform experiments to measure key mechanical properties on a range of materials (Testing), use materials selection charts to compare the properties measured with those of other materials (Comparison), and then use this information to get at the fundamental concepts behind the properties at hand (Origin). The T-C-O approach uses both laboratory and lecture to promote true learning in the mechanical behavior of materials. A state-of-the-art tensile testing system is also being used in this project. This system, of appropriate size and capability for undergraduate use, is the cornerstone of the mechanical behavior of materials laboratory facility. Several sets of T-C-O experiments are presented at the sophomore through senior level for materials engineers and other engineering disciplines where students can use the new tensile testing system, plus other mechanical testing equipment, to discover the nature of the mechanical behavior of materials. The T-C-O method is being evaluated by student surveys at several levels and by Beta Testing at San Jose State University and the University of California, Davis. Successful results can be disseminated to the materials and mechanics communities at the Beta Test sites, by presentation at a national technical meeting, and by publication in a refereed technical journal.

本项目的重点是加强结构材料力学行为领域的本科材料工程教育。提出了一种创新的方法，学生通过实验来测量一系列材料的关键机械性能（测试），使用材料选择图表将测量的性能与其他材料的性能进行比较（比较），然后使用这些信息来获得手头属性背后的基本概念（起源）。T-C-O方法使用实验室和课堂来促进材料力学行为的真正学习。该项目还使用了最先进的拉伸测试系统。该系统具有适合本科生使用的大小和能力，是材料力学行为实验室设施的基石。本课程在高二至高二阶段为材料工程师和其他工程学科提供了几套T-C-O实验，学生可以使用新的拉伸测试系统，以及其他力学测试设备，来发现材料力学行为的本质。圣荷西州立大学（San Jose State University）和加州大学戴维斯分校（University of California, Davis）的Beta测试正在对不同层次的学生调查和T-C-O方法进行评估。成功的结果可以在Beta测试站点的材料和力学社区中传播，通过在国家技术会议上的介绍，以及在经过评审的技术期刊上发表。
