Abstract

The damage variables were defined by the microstructure of rod-shaped eutectic with parallel nano-micron fibers. The maximum strain criterion was used for determining the loading function. According to the attenuation characteristic of eutectic rigidity, the critical fracture stress of the damage rod-shaped eutectic was obtained by damage variable maximizing. On the basis of the work done by frictional force over the pull-out length, bridging toughening mechanism and pull-out toughening mechanism of damage rod-shaped eutectics were constructed. The result shows that damage in the eutectic reduces the eutectic rigidity, thus fracture strength decreases and the eutectic contribution to composite ceramic bridging toughening and pull-out toughening decreases.
