Impact toughness and fracture toughness

WitrynaToughness is the ability of a material to absorb energy and plastically deform without fracturing. One definition of toughness (for high-strain rate, fracture toughness) is that it is a property that is indicative of a material’s resistance to fracture when a crack (or other stress-concentrating defect) is present.Toughness is typically measured by the … Witryna1 lis 2024 · Impact toughness properties of four kinds of HSS were investigated with the nominal yield strength of 460, 690, 800 and 960 MPa, respectively. The specialty of impact toughness among base metal, HAZ and weld metal were also measured and compared. Combined with the SEM microstructure analysis, the fracture mechanism …
