Bruddfasthet
Bruddfasthet is a term used in some Nordic languages, notably Swedish and Norwegian, to describe the fracture resistance of materials—their ability to withstand the formation and growth of cracks under applied loads. It encompasses both crack initiation and crack propagation resistance and is closely related to, but not identical with, general strength or hardness. In English-language literature, the concept is often discussed under fracture toughness or crack-growth resistance, with quantitative measures such as the critical stress intensity factor K_IC or J_IC used to quantify resistance to fracture.
Evaluation of bruddfasthet typically relies on standardized fracture tests, such as compact tension (CT), single-edge notched
In engineering practice, bruddfasthet guides safety margins and failure analyses for structural components, pressure vessels, and
