Keywords:
Composite layer cylinder shell, Strain stress state, Variational method, High-order shear deformationAbstract
The paper presents the problem of analyzing the stress state of the composite cylinder shell under the effect of thermomechanical action on the basis of the theory of high-order sliding strain of 3D type. In this paper, the three-dimensional equations in the theory of nonlinear elasticity of the shell under the effect of thermo-mechanical loads are established into two-dimensional nonlinear equations for the cylindrical shell by using the decomposition method. and analyze the displacement field into a series of polynomial functions according to the shell thickness. On the basis of the obtained equations, set up a calculation program, compare and verify with the published results. From there, the survey and analysis of the thermomechanical response of the composite cylinder shell is applied.
