Compact tension specimen
The compact tensile specimen is a standardized specimen geometry for measuring fracture strength under tensile loading. It is used to determine the mechanical properties of materials.
Physico-chemical Mechanism of Action
The compact tensile specimen consists of a straight bar with a constant cross-section and two flanks arranged parallel to the length. Under tensile loading, stresses build up until the material's fracture strength is reached.
Metallurgical Relevance & Risks in Welding
The compact tensile specimen provides important information about fracture strength and the behavior of materials under tensile loading. Poor welding procedures can reduce fracture strength, leading to cracks or failure.
Workshop Practice & Instructions for Use
To correctly perform a compact tensile test, the material must be subjected to a specific tensile stress range. Stress is continuously increased until the material breaks. The maximum stress the material withstands is the fracture strength. This value should be regularly checked and documented to ensure the material maintains its mechanical properties.
