frakturstyrka
Frakturstyrka, also known as fracture toughness, is a material property that describes the ability of a material to resist the propagation of cracks. It is a critical parameter in fracture mechanics, which is the study of the propagation of cracks in materials. The concept of fracture toughness is particularly important in the design and analysis of structures and components that are subjected to dynamic or cyclic loading, such as aircraft, pressure vessels, and bridges.
Fracture toughness is typically measured in units of stress intensity factor (K) or energy release rate (G).
Fracture toughness is influenced by various factors, including the material's microstructure, the presence of defects or
In engineering design, fracture toughness is used to determine the maximum allowable stress or strain that
