Recommendations for Assessment of Stress-Strain State of the Metal Cylindrical Specimen When Performing the Tensile Test.

Experimental Study of Tensile Failure of the Steel Specimen.

“…The mechanical properties of material during tensile are calculated based on this dependence. Currently, the large number of studies (theoretical and practical) have been conducted on this topic [2][3][4][5][6][7][8][9][10]. Elastic limit, yield strength and tensile strength of materials with different carbon content were determined.…”

The Dependencies of Tension Strain From Stress of the Flat Steel Specimen.

“…In particular, the rational strain rates of the metal specimens, the methods for eliminating errors of the calculation of the stress-strain state of material were determined. The analytical dependencies of equivalent elastic strain, maximum shear elastic strain, equivalent stress and the temperature of material from the elongation of the round specimen and the applied load were obtained in the work [10]. Let us consider the tension process from elastic strains to material fracture on the example of changing the calculated values of the elastic volume ratio, the von Mises stress, the elastic strain energy density, the first invariant of the elastic strain tensor, the second invariant of the deviatoric elastic strain tensor, the Tresca stress, volumetric strain, and the Lode angle for the flat specimen.…”
