摘要：
Particle-reinforced composites offer high stiffness, high strength, and low density, while maintaining reasonable cost. Their mechanical properties, e.g. tensile strength, depend upon reinforcement characteristics and matrix microstructure. In this study, we have performed in situ x-ray synchrotron tomography to understand the damage in 2080 aluminum alloy reinforced with SiC particles in three dimensions. The initial 3D reconstructed microstructure was used as a basis for extended finite element model (XFEM) to simulate damage in the composite when tensile loading is applied.
