Abstract The review examines the works in which the results of the analysis of experimental data for secondary creep and creep rupture are presented. These experimental data have been obtained for various metallic materials under uniaxial tension and complex stress conditions. The results of the analysis of these experimental data are given in the review. © 2022 The Authors. Published by ELSEVIER B.V.

Keywords: Secondary creep; creep rupture; starting creep stress; break creep stress; rupture time; complex stress; equivalent stress. 1. Introduction For the first time, the creep property has discovered by Navier (1826) from the analysis of the results of mechanical tests of tension copper and lead plates under the action of a stationary axial force, as well as inflated hollow copper balls under the action of internal pressure, while accurate measurements were not carried out. The creep curves (the dependence of elongation on time) were first obtained by Vicat (1834) when stretching sections of iron wire with different stationary axial forces, while for 2 years the maximum relative elongation was equal to 30%. These mechanical test results are obtained at room temperature. When heated to a high temperature, the results of such mechanical tests were first obtained in the first half of the XX century, where Andrade (1910) obtained creep 15th International Conference on Mechanics, Resource and Diagnostics of Materials and Stru tures Review of the analysis of the experimental data on secondary creep and creep rupture Vladlen Nazarov* Institute of Mechanics Lomonosov Moscow State University, 1 Michurinsky Avenue, Moscow, 119192, Russian Federation Abstract The review examines the works in which the results of the analysis of experimental data for secondary creep and creep rupture are pres nted.
