Breaking vs. smooth deformation: The two ways glasses fail

Caption

The stress–strain curves illustrate the contrasting mechanical responses of brittle and ductile materials. Brittle materials fracture suddenly after reaching their yield point, whereas ductile materials undergo smooth deformation before failure. The breaking window glass represents brittle failure, while the deforming butter shows ductile deformation.
