a margin of safety, asymmetric loading, stress concentration, limit stateAbstract
The method of calculation of margin of safety of details of the machine-building designs subject to joint influence of static and cyclic loadings is considered. The main attention is paid to an assessment of the maximum limit tension, characteristic for asymmetric loading of constructional materials, taking into account concentration of tension as one of the major factors inherent in real constructive elements. Used previously developed model the limit state of structural materials in the form of power of transcendental functions. The models provide a good agreement of the results of calculation of the limit state of structural materials with the experimental data with a minimum of preliminary studies. The offered approach provides more correct calculation of margin of safety at implementation of project works.
