Micro-Mechanics of Failure-Resistant Materials

该MRG提供了一个为期三年的综合计划，致力于用微观力学的方法来设计和加工在技术应用中具有最佳抗故障能力的复合材料。研究的重点是金属基复合材料和陶瓷基复合材料。金属间化合物也将被包括在内，因为它们在高温下具有提供韧性和强度的潜力。学员将(I)通过确定材料的微观结构，(Ii)通过建立部件及其界面的本构模型，(Iii)通过对断裂过程的数值模拟，以及(Iv)通过整合对材料性能的实验测量的模拟响应，来发展对失效机理的定量理解。这项研究将由教师、博士后助理、研究生和本科生进行。

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.
