If a complex structural configuration is impacted and energy absorption measured as a function of temperature, it will generally be observed, particularly with steel components, that a transition in the behavior takes place with test temperature. At high test temperatures, considerable energy is absorbed and fibrous fracture occurs at low test temperatures, little energy is absorbed and the fracture is very brittle. The transition region over which this change takes place may cover a wide or narrow temperature range. This general behavior pattern characterizes the so-called brittle behavior problem. Design attempts against brittle behavior are presented.
