Термоупругое напряженное состояние многослойной трубы с защитным слоем из дюралюминия и углепластика

Abstract

On the basis of the classical theory of elasticity of an anisotropic body compared stress-strain state of multilayer thick-walled cylinder of finite length under the action of internal pressure and temperature. The protective layer of the cylinder is made of aluminium and carbon fiber. Kinematic and static contact conditions on the surfaces of adjacent layers are considered ideal. The solution of the problem was obtained in axisymmetric setting. The internal pressure and temperature load change sinusoidal the length of the cylinder.It is noted that the replacement of the dural protective layer composite pipes in carbon, significantly affects its stress state. Protective layer of carbon fiber was more effective version when comparing the stress-strain state of the considered design options cylinders.
