operate structures at this temperature. Thus, the limiting state for the investigated muffle design - the formation of discontinuity at a certain point of the muffle design occurs at T = 600° C. 5. CONCLUSION Thus, the proposed method makes it possible to determine the limiting state of thin-walled metal structures operated in corrosive environments and loaded with thermal and mechanical loads.
