In this dissertation, an unprecedented and thorough investigation is conducted into the linear and nonlinear free vibrations of magneto-electro-elastic (MEE) curved beams characterized by deep curvature. Additionally, an exhaustive examination is carried out for the first time on MEE truncated conical panels exhibiting deep curvature. Furthermore, a meticulous exploration is undertaken for the linear and nonlinear dynamic analyses of these panels subjected to blast loads. In the context of all the aforementioned analyses, careful consideration is given to the coupling effects between their mechanical, electrical, and magnetic behaviors. In separate assessments, the behavior of each of the aforementioned structures has been scrutinized with precision concerning two distinct constituent materials. The first category encompasses composite single-layer structures, where the matrix phase comprises MEE material reinforced with carbon nanotubes (CNTs) in various uniform and functionally graded (FG) distributions. The second category involves sandwich structures comprising two outer homogeneous layers of MEE material and a composite core reinforced with CNTs in diverse uniform and FG configurations.
In the present era, structures made of MEE materials find a wide range of applications in advanced engineering industries. One of the latest and most advanced applications of such structures is their use as protective coatings against electromagnetic waves, owing to specific advancements or characteristics. Due to the coupling between the mechanical, electrical, and magnetic behaviors of these structures, the investigation of their mechanical behavior generally requires consideration of this coupling. However, as far as the author is aware, no research has been reported to date on the nonlinear free vibrations, linear and nonlinear dynamic analysis of curved beams, and truncated conical panels made of these materials, considering the mentioned coupling.
