摘要：

In this paper, a combined experimetal-computational approach is used to study the evolution of microscopic damage to cause failure in commercial SIC particle reinforced DRA's. An interrupted testing technique is invoked where the load is halted in the material instability zone, following necking but prior to fracture. Sample microstructures in the severely necked region are microscopically examined in 3D using a serial sectioning method. The micrographs are then stacked sequentially on a computer to reconstruct 3D microstructures. Various characterization functions of geometric parameters are generated and sensitivity analysis is conducted to explore the influence of morphological parameters on damage. Modeling of the initiation and propagation of damage for 2D micrographs are conducted with Voronoi Cell Finite Element Method (VCFEM).
