brittle, and the most ductile ceramics will be more brittle than most metals. Polymers have a behavior ranging from brittle (at tempera-tures below their glass transition temperature) to very deformable (in a nonlinear elastic material, such as rubber). The fracture toughness is a good measure of the resistance of a material to failure and is
