Micro-Mechanics of Failure-Resistant Materials

该MRG提供了一个为期三年的综合方案，致力于 设计和加工的微观力学方法 技术上具有最佳抗破坏性的复合材料 应用. 该研究将集中在金属基体和 陶瓷基复合材料 金属间化合物也将包括在内 因为它们具有提供韧性和 在高温下的强度。 与会者将制定一个 对失效机理的定量理解 (i)通过对材料微观结构的测定， (ii)通过开发组件的本构模型， 它们的界面，（iii）通过断裂的数值模拟 过程，以及（iv）通过集成模拟响应， 材料性能的实验测量。 研究 将由教师、博士后、 研究生和本科生。

This MRG provides a three-year integrated program devoted to a micro-mechanics approach to the design and processing of composites with optimal failure resistance in technical applications. The research will focus on metal-matrix and ceramic-matrix composites. Intermetallics will also be included because of their potential for providing both toughness and strength at high temperatures. The participants will develop a quantitative understanding of the mechanics of failure (i) through determination of the microstructure of the materials, (ii) by development of constitutive models for the components and their interfaces, (iii) by numerical simulation of the fracture process, and (iv) by integration of simulated responses to experimental measurements of materials properties. The research will be carried out by faculty, post-doctoral associates, graduate students and undergraduate students.
