Abstract In the present study, thermoelastic analysis of laminated composite and sandwich shells (cylindrical/spherical) is presented using fifth-order shear and normal deformation theory. The significant characteristic of the present theory is that it includes the effects of both transverse shear and normal deformations. The mathematical formulation uses the principle of virtual work to derive the variationally consistent governing equations and traction free boundary conditions. To obtain the static solution, these governing equations are solved by employing Navier’s solution technique. The shell is subjected to a mechanical/thermal load sinusoidally distributed over the top surface of the shell. The thermal load linearly varies across the thickness of the shell. The present results are compared with other higher-order models and 3D elasticity solution wherever possible. Thermal stresses presented in this study will act as a benchmark for the future work.

考虑横向剪切和法向变形影响的层压复合材料和夹心壳的热弹性分析

摘要 在本研究中，使用五阶剪切和法向变形理论对层压复合材料和夹心壳（圆柱形/球形）进行热弹性分析。本理论的显着特点是它包括横向剪切和法向变形的影响。数学公式使用虚功原理来推导变分一致的控制方程和无牵引边界条件。为了获得静态解，这些控制方程通过使用 Navier 的求解技术来求解。壳体承受正弦分布在壳体顶面上的机械/热载荷。热负荷随壳体厚度呈线性变化。尽可能将当前结果与其他高阶模型和 3D 弹性解决方案进行比较。本研究中提出的热应力将作为未来工作的基准。
