Summary

A two-dimensional analytical model that describes the fracture toughening mechanism in ceramic/metal composites is presented. Toughnesses greater than that of the ceramic constituent alone can be attributed to the clamping of the crack by metal ligaments that bridge the crack surfaces. Calculations of the fracture toughnesses of several composite systems are in good agreement with experimentally determined values.
