Non-linear Behavior of Smart Magneto-Electro-Elastic Hyperboloid Shell

Magneto-electro-elastic (MEE) materials have piqued the interest of researchers worldwide due to their high energy conversion rates in the magnetic field, electric field, and elastic field. In this research paper, geometrically nonlinear response of Magneto‐electro‐elastic composite materials (MEE) shell structure is investigated. The proposed finite element (FE) model is based on the Kirchhoff shell theory. A four-node finite shell element is used to analyze and predict the nonlinear behavior of smart structures. Discrete system of geometrically nonlinear equilibrium equations are solved by the Newton-Raphson method. Numerical results of hyperboloid shell are compared with works from literature in order to highlight the feasibility and effectiveness of the current finite element model, notably for thin structures. A good agreement is obtained and the static response of MEE under large deformations and finite rotations. The effect of the volume fraction change of the MEE material on the large deflection of the smart magneto-electro-elastic hyperboloid shell is examined.
