Analytical description of material deformation curves

Abstract

Based on an Arrhenius-type equation proposed by the logarithmic law for the curves of deformation of materials under tension, compression, bending and torsion. The notion of logarithmic strain Є=ln(ε). After adjustment in the coordinates with a logarithmic strain along the horizontal axis, the deformation curves are rectilinear with a slope equal to the logarithmic strain hardening coefficient. It also proposed a law that contains the arch, which bette r describes the initial stages of deformation curves. Approximated by a series of curves of deformation of materials with the use of Excel and Origin, which has shown the suitability of the proposed laws for use. Full text download
