    • Analytical solutions for nonlinear vibration of porous functionally graded sandwich plate subjected to blast loading
    Tác giả : Tran, Quoc Quan; Do, Thi Thu Ha; Nguyen, Dinh Duc;  Người hướng dẫn: -;  Đồng tác giả: - (2022)

    This paper presents the nonlinear vibration of porous functionally graded sandwich plate on elastic foundations subjected to blast loading by the analytical approach. The sandwich plate consists of two FGM face sheets and a homogeneous core which is made from metal or ceramic. Two types of porosity distribution, including evenly and unevenly distributed porosity have been considered for sandwich plate. The material properties of sandwich plate are assumed to vary in the thickness direction according to simple power law distribution with a volume fraction index and a porosity coefficient. The blast loading is assumed to be uniformly distributed on the surface of the sandwich plate and modeled by an exponential function. The Reddy’s higher order shear deformation theory with von Kármá...
    • Vibration analysis of auxetic laminated plate with magneto-electro-elastic face sheets subjected to blast loading
    Tác giả : Ngo, Dinh Dat; Tran, Quoc Quan; Nguyen, Dinh Duc;  Người hướng dẫn: -;  Đồng tác giả: - (2022)

    Mathematic modeling and analytical approach are presented for nonlinear vibration analysis of laminated plate with auxetic honeycomb core and magneto-electro-elastic face sheets supported by Pasternak-type elastic foundations. The laminated plate is subjected to the simultaneous action of blast, thermal, electric and magnetic loadings. The mechanical properties of auxetic core including negative Poisson’s ratio are assumed to depend on the geometrical parameters of the unit cells and elastic modulus of original material. The volume fraction of two components of each magneto-electro-elastic face sheet is chosen equally.

The volume fraction of two components of each magneto-electro-elastic face sheet is chosen equally. The nonlinear motion equations and the geometrical compatibility equation are established by using Reddy’s higher order shear deformation plate theory taking into acc...
