Description
The maximum impact from a hard blow that a material can withstand before breaking. The standard testing methods for impact strength are the Charpy method and the Izod method. Both methods place a notch in the material on the side opposite the striking position. This localizes the stress and induces a brittle fracture that is independent of the effects of velocity. Both tests provide the impact strength in foot-pounds of energy required for breakage. A high impact strength indicates that a material is tough and not brittle. Impact strength tests are often done on metals, hard rubber, plastics, portland cement and glass.
