"WebBrittle materials absorb relatively little energy prior to fracture, even those of high strength. In brittle fracture (transgranular cleavage), no apparent plastic deformation takes place before fracture. Toughness can also be defined with respect to regions of a stress–strain diagram (for low-strain rate). " - Brittle in science
