Она определяется по энергии, затрачиваемой на разрушение, в качестве показателя которой принимается ударная вязкость, и по виду излома образцов, в качестве показателя которого принимается доля вязкой составляющей в изломе
It is determined by the energy consumed by the destruction, as an indicator of whom impact strength and fracture samples as an indicator of which was adopted by the proportion of the viscous component of fracture
It is determined by the energy expended in the destruction, as a measure which is adopted toughness, and fracture type of samples as a measure of the proportion of which is taken shear fracture
it is determined by the energy затрачиваемой to destruction, which was adopted as a measure of toughness, and mean kink samples as an indicator which is the viscous part of the изломе
