The research to be performed on this RIA award will evaluate the effect on the matrix constraint - and thus on creep resistance - of diffusional relaxation and interface slip along the matrix- reinforcement interface of intermetallic matrix composites. Unit cell models will be used and solved by the finite element method. AS coupled analysis of slip and diffusion, along with fiber cracking, will also be performed to investigate the net effect of the reinforcement size.//

对该RIA奖进行的研究将评估 对基体约束的影响-从而对抗蠕变性的影响- 扩散弛豫和界面沿基体沿着滑移- 金属间基复合材料的增强界面。 单元 将使用单元模型并通过有限元法求解。 沿着纤维滑移扩散耦合分析 开裂，也将进行调查的净效应， 增强尺寸。//
