A Fracture is the separation of an object or material into two or more pieces under the action of stress. Depending on the substance which is Fractured, a Fracture reduces strength or inhibits transmission of light . Fracture strength, also known as breaking strength, is the stress at which a specimen fails via Fracture. This is usually determined for a given specimen by a tensile test, which charts the stress-strain curve . Ductile materials have a Fracture strength lower than the ultimate tensile strength , whereas in brittle materials the Fracture strength is equivalent to the UTS. If a ductile material reaches its ultimate tensile strength in a load-controlled situation,[Note 1] it will continue to deform, with no additional load application, until it ruptures. The true stress on the material at the time of rupture is known as the breaking strength. In amorphous solids, by contrast, the lack of a crystalline structure results in a conchoidal Fracture, with cracks proceeding normal to the applied tension.
