EFFECT OF GRAVITY ON THE STRESS-STRAIN STATE OF THICK-WALLED CYLINDRICAL PIPE WITH INCLUDED
As part of the small parameter method examines the effect of gravity on the stress-strain state of a cylindrical tube with an elastic-visco-plastic inclusion under the action of a uniform radial internal and external loads. In the plastic zone of the pipe material, the model described by the relations A.N. Sporykhin that takes into account both elastic and viscous and plastic properties of the medium with the physical and mechanical parameters of the non-inclusion of material parameters. The estimation of the influence of gravity and the physical and mechanical parameters of the environment on the development of elastic-plastic boundary and the stress state of the structure.
