摘要

准确评估层合圆柱壳在不同载荷作用下的三维热弹性分析对其安全设计具有重要意义。在本研究中,我们提出了均匀局域热边界条件下层合正交各向异性圆柱壳的三维热弹性解。对于均匀正交各向异性层,引入薄层法处理热传导方程和弹性方程。基于特征方程法和伪stroh形式,导出了齐次层物理量的一般解。采用传播矩阵法处理多层介质。得到了层合圆柱壳的封闭解。最后以对流换热边界条件下的三层圆柱壳为例,验证了该方法的正确性。现有方法具有较好的收敛性,所预测的物理量与有限元数值结果吻合较好。最后,用该方法得到了均匀局域热边界条件下三层正交各向异性圆柱壳的数值解。本文提出的封闭解可用于复杂边界条件下层合圆柱壳的三维热弹性分析。

Three-dimensional thermoelastic analysis of orthotropic laminated cylindrical shells subjected to uniformly localized thermal boundary conditions
Abstract Accurate evaluation of three-dimensional (3D) thermal-elastic analysis of laminated cylindrical shells under different loads has a significant impact on their safety design. In this study, we present a 3D thermoelastic solution of laminated orthotropic cylindrical shells subjected to uniformly localized thermal boundary conditions. For a homogeneous orthotropic layer, a thinning layer approach is introduced to deal with the heat conduction equation and the elastic equation. Based on the eigenequation method and pseudo-Stroh formalism, general solutions for physical quantities of a homogeneous layer are derived. The propagator matrix method is used to deal with multilayered media. A closed form solution for the laminated cylindrical shells is obtained. A numerical example of a 3-layered cylindrical shell subjected to convective heat transfer boundary conditions is presented to verify the solutions’ correctness. An excellent convergence of the current approach is found and the physical quantities predicted by the current method agree well with the numerical results by the finite element method. Finally, the numerical solutions of a 3-layered orthotropic cylindrical shell subjected to uniformly localized thermal boundary conditions are obtained by the current method. The closed form solution presented in this article can be used for 3D thermoelastic analysis of laminated cylindrical shells under complex boundary conditions.
