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.
