This paper presents a static analysis of large deflection behavior in functionally graded magneto-electro-elastic porous (FG-MEEP) cylindrical shells using the geometric fully nonlinear finite element (FE) method. The governing equations are derived based on first-order shear deformation theory (FOSD) and strain-displacement relationship considering rotations. A dynamic model is developed employing Hamiltonian principle. Four gradient models temperature variation along thickness constructed, such as uniform, linear, sinusoidal heat conduction. Moreover, porosity effects FG-U, FG-V, FG-O FG-X distributions taken into account. accuracy efficiency proposed verified by comparing with results existing literature commercial software. subsequent extensive research conducted to investigate influence various parameters mechanical response FG-MEEP structure. It concluded that adopting rotation (LRT) can yield more precise outcomes for structures experiencing significant deformations under thermal environments, providing valuable insights future structures.
