Non-Linear Response of an Intelligent FGP-MEE Tapered Panel

This paper focuses on the geometrically nonlinear analysis of a composite mem-brane structure, termed FGP-MEE, comprising Functionally Graded Porous Ma-terial (FGPM) integrated with surface-bonded Magneto-Electro-Elastic (MEE) layers. The model utilized in this study uses the FSDT theory, which necessi-tates the incorporation of a shear correction component due to the consistent adoption of constant transverse shear. The Newton-Raphson approach is then utilized to form a discrete system of equilibrium equations that consider geomet-ric nonlinearity. In this examination, the assumption that the material character-istics of the porous FGM structures change progressively across the thickness of the shell is made, adhering to a power-law function and porosity distributions. To confirm the dependability and efficiency of this approach, we cross-reference our findings with those of pertinent studies. These numerical findings provide insights into how the power law index and porosity coefficients impact the non-linear behaviors of intelligent Functionally Graded Porous Material (FGPM) structures.
