Abstract

Способ определения механических свойств металлов, включающий осевое растяжение плоских и круглых образцов с фиксированной скоростью деформации, и температуры испытания, отличающийся тем, что, с целью прогнозирования эксплуатационной надежности металлов и сопротивления их к разрушению, коэффициент динамической вязкости металлов µ, и эффективную энергию разрушения Aопределяют по формулам С.В.Серикова:для плоского образца,,для круглого образца,,здесь- соответственно предел прочности, предел текучести и относительное удлинение металлов при растяжении стандартных образцов, а также- скорость деформации при которой растягивается образец, E - модуль Юнга, c - скорость звука продольных волн в металле.A method for determining the mechanical properties of metals, including axial tension of flat and round samples with a fixed strain rate, and test temperature, characterized in that, in order to predict the operational reliability of metals and their resistance to destruction, the coefficient of dynamic viscosity of metals µ, and the effective fracture energy A according to the formulas of S.V.Serikov: for a flat specimen, for a round specimen, here is the tensile strength, yield strength and elongation of metals, respectively in tension of standard samples, as well as the strain rate at which the sample is stretched, E is Young's modulus, c is the speed of sound of longitudinal waves in a metal.
