To be specific, Maclaurin, trigonometric, exponential and zig-zag functions are employed. The employed refined models are based on the equivalent single layer theories. A simply supported shell is subjected to different mechanical loads, specifically: bi-sinusoidal, uniform, patch, hydrostatic pressure and point load. The governing equations are derived from the Principle of Virtual displacement and solved via Navier-Type closed form solutions. The results are compared with results from Layer-wise solutions and different higher order shear deformation theories available. It is shown that refined models with non-polynomial terms are able to accurately predict the through-the-thickness displacement and stress distributions maintaining less computational effort compared to a Layer-wise models.}, keywords = {Shell,Laminated composite,Carrera Unified Formulation (CUF),Doubly-curvature}, url = {https://jacm.scu.ac.ir/article_14263.html}, eprint = {https://jacm.scu.ac.ir/article_14263_464f93f56f736b678cf0b8c59414f8db.pdf} }
