The objective of this project is to determine stress and strain distributions over length scales of less than a micron through the development of novel experimental and computational techniques. These techniques will be applied to determine the micromechanical response at fiber/matrix interface of high performance metal matrix composites. The microscopic response of the fiber/matrix interface is believed to affect a wide range of mechanical properties of composites at the extreme conditions of high stress, temperature and cyclic loading. A key facet of the project is the provision of research opportunities for minority students majoring in engineering at Florida A&M University.

该项目的目标是通过开发新颖的实验和计算技术来确定小于一微米的长度尺度上的应力和应变分布。 这些技术将用于确定高性能金属基复合材料纤维/基体界面处的微机械响应。 纤维/基体界面的微观响应被认为会影响复合材料在高应力、温度和循环载荷的极端条件下的广泛机械性能。 该项目的一个关键方面是为佛罗里达农工大学工程专业的少数族裔学生提供研究机会。
