Stochastic model of visco-brittle transition in steels
Autor: A. G. Kazantsev, V. M. Markochev, S. Yu. Korolev
Publikováno v: Industrial laboratory. Diagnostics of materials. 88:53-60
A stochastic model of ductile-brittle (DB) transition based on a bimodal representation of random processes the critical temperature range of brittleness is proposed. Modeling was carried out in two stages. The results of impact tests of more than 12

The inverse strength problem for evaluation of bending stresses in pipelines during ground movements
Autor: V. M. Markochev
Publikováno v: Industrial laboratory. Diagnostics of materials. 87:68-76
Three variants of the engineering solution of inverse problems regarding the strength of pipeline sections bent as a result of ground movements or during an earthquake are proposed. The feature of this approach consists in calculation of stresses not

Modeling of elastic-plastic deformation of the ring parts as applied to the analysis of the results of testing the material of the fuel-element cladding
Autor: V. M. Markochev
Publikováno v: Industrial laboratory. Diagnostics of materials. 87:67-75
An analytical formula for a smooth description of the tension diagram of EK-181 steel and a method for rearranging the diagram when changing the direction of deformation are proposed for the first time. The process of straightening a quarter of an an

COMPUTER SIMULATION OF COMBINED SPLITTING FORCE: STRAIN LOADING OF DOUBLE-BEAM SAMPLES
Autor: V. M. Markochev, V. Yu. Gol'tsev
Publikováno v: Industrial laboratory. Diagnostics of materials. 84:72-78
The purpose of this work is to study possible schemes of loading double-cantilever beam (DCB) specimens to replenish the arsenal of the methods used in their testing. Mathematical analysis of ten different modes of specimen loading is carried out for

A mathematical model of transition of the material from elastic to elasto-plastic state
Autor: V. M. Markochev
Publikováno v: Industrial laboratory. Diagnostics of materials. 84:55-60
The goal of this study is to develop a mathematical model of the transition of the structural material from elastic state to elastoplastic state upon tension. The model is based on a modified three-parameter transition operator from one mathematical
