Transverse creep induced by interfacial diffusion in fiber-reinforced composites: A micromechanics model and computational validation

Interface diffusion is an important weakening mechanism in the creep behavior of metal matrix composites at high temperatures. The increase in the creep strength of composite materials caused by stress transfer from matrix to rigid reinforcements may be totally offset by rapid interface diffusion. However, in-depth understanding of the complex multi-field coupling process of interface diffusion remains lacking. Here, we present a theoretical...
