RIA: The Effect of Interface Diffusion and Slip on the Creep Resistance of Fiber and Particulate Composite Materials

这项RIA奖的研究将评估金属间基复合材料沿基体-增强界面的扩散松弛和界面滑移对基体约束的影响，从而对抗蠕变性能产生影响。将采用单元胞模型，并采用有限元法求解。滑移和扩散以及纤维开裂的AS耦合分析也将进行，以研究钢筋尺寸的净效应。//

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.//
