    The paper proposes methodology for bar calculation in the case of elastic and plastic non-flat bending. It is shown how to determine an ultimate bending moment with single and two axes of symmetry in cross-section, residual stresses in case of unloading.ΠŸΡ€Π΅Π΄Π»ΠΎΠΆΠ΅Π½Π° ΠΌΠ΅Ρ‚ΠΎΠ΄ΠΈΠΊΠ° расчСта бруса ΠΏΡ€ΠΈ упругопластичСском нСплоском ΠΈΠ·Π³ΠΈΠ±Π΅.

    The paper shows that gas-thermal coatings on the product surface may be considered on a first approximation as bimetallic material. Such approach permits to make calculations and determine residual stresses on the basis of multi-layer plate theory, mechanics of continuous medium and thermoelasticity.Показано, Ρ‡Ρ‚ΠΎ газотСрмичСскиС покрытия Π½Π° повСрхности издСлия ΠΌΠΎΠΆΠ½ΠΎ Ρ€Π°ΡΡΠΌΠ°Ρ‚Ρ€ΠΈΠ²Π°Ρ‚ΡŒ Π² ΠΏΠ΅Ρ€Π²ΠΎΠΌ ΠΏΡ€ΠΈΠ±Π»ΠΈΠΆΠ΅Π½ΠΈΠΈ ΠΊΠ°ΠΊ бимСталличСский ΠΌΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π», Ρ‡Ρ‚ΠΎ позволяСт ΠΏΡ€ΠΎΠ²ΠΎΠ΄ΠΈΡ‚ΡŒ расчСты ΠΈ ΠΎΠΏΡ€Π΅Π΄Π΅Π»ΡΡ‚ΡŒ остаточныС напряТСния, ΠΎΡΠ½ΠΎΠ²Ρ‹Π²Π°ΡΡΡŒ Π½Π° Ρ‚Π΅ΠΎΡ€ΠΈΠΈ многослойных пластин, ΠΌΠ΅Ρ…Π°Π½ΠΈΠΊΠΈ ΡΠΏΠ»ΠΎΡˆΠ½Ρ‹Ρ… срСд ΠΈ тСрмоупругости
