摘要：

The objective of this work is to study the influence of the loading path on the lifetime of self-healing ceramic matrix composites. The loading can be of different types: mechanical, thermal or chemical. The self-healing process consists of filling some cracks with an oxide plug, thus limiting the diffusion of oxygen toward the fibers. The three phenomena with the greatest influence on the lifetime are (a) crack opening, governed by the mechanical part of the loading, (b) volatilization of the oxide plug, and (c) diffusion governed by both the chemical part of the loading and the activation temperature of the chemical reactions. The examples given show the influence of each part of the loading path.
