Semi-analytical solution of clamped-clamped rotating thick conical pressure vessels under two-dimensional thermal loading

Fatemeh Ramezani, Mohammad Zamani Nejad and Mehdi Ghannad

Abstract

In this paper, the thermoelastic behavior of an axisymmetric clamped–clamped rotating thick truncated cone under mechanical loading and bi-directional thermal loading is investigated. The governing equations are formulated as a set of non homogeneous ordinary differential equations with variable coefficients. The solution of these equations is obtained by applying boundary conditions and ensuring continuity between the layers using the multi-layer method (MLM) as a semi-analytical approach based on the first-order shear deformation theory (FSDT). The results obtained from this study are compared with finite element method (FEM) simulations, demonstrating good agreement.
