摘要：
This article presents a finite element (FE) model using curved isoparametric elements (Q8) to examine the static, stress and free vibration characteristics of laminated composite conoidal shells (LCCS) with displacements fields based on the Carrera Unified Formulation (CUF). CUF not only integrates an equivalent thickness concept with user-defined deformation theory order but also can take up curvature effects in strain displacement fields making it suitable for the analysis of thin and moderately thick LCCS. The study investigates the static and free vibration characteristics of thin and moderately thick LCCS under diverse practical boundary and loading conditions.
