Bruddstyrke
Bruddstyrke, usually translated as ultimate tensile strength (UTS), is the maximum stress a material can withstand while being stretched before it fails or fractures. It is expressed as stress, typically in megapascals (MPa), and is obtained from a tensile test in which a standardized specimen is pulled until fracture. The stress at the moment of rupture defines the bruddstyrke. It is influenced by the material’s microstructure, temperature, strain rate, and the presence of flaws.
Bruddstyrke is related to, but distinct from, yield strength. Yield strength marks the onset of permanent plastic
Measurement and standards: Bruddstyrke is determined on a universal testing machine through a tensile test on
Applications and limitations: Bruddstyrke is a key parameter in material selection and structural design, but it
Typical ranges: Metals generally exhibit bruddstyrke from hundreds of MPa to over 1 GPa; polymers 20–100 MPa;
