Indentation Determination of the Fracture Toughness of Steels at Various Temperatures
Tóm tắt
The state of the art in the field of estimating the fracture toughness of ductile steels using the parameters of indentation by a spherical indenter is considered. Relations to calculate the specific indentation energy of a sphere using the diameter of a recovered impression are received. A method is developed to estimate the critical stress intensity factor for the plane strain state of pipeline and vessel steels using the parameters of indentation by a spherical indenter performed on a standard stationary Brinell hardness tester.
