As a first endeavour, nonlinear dynamic response of the glass fibre-reinforced​ epoxy (GRE) laminated composite cylindrical shells under an impulse load is investigated based on first-order shear deformation theory (FSDT) shells. Green’s strain and von Kármán hypothesis are assumed to consider geometrical nonlinearity due large in model. A new solution procedure composed differential quadrature...

Torsional vibrations of composite poroelastic dissipative spherical shell are investigated in the framework of Biot’s extension theory.Here composite poroelastic spherical shell consists of two spherical shells, one is placed on other, and both are made of different poroelastic materials. Consideration of the stress-free boundaries of outer surface and the perfect bonding between two shells lea...

In this research, the influence of carbon nanotubes agglomeration on buckling behavior multi-phase CNTs/fiber/polymer/metal composite laminates cylindrical shells under hydrostatic pressure was investigated. Governing equations were derived according to Kirchhoff-Love’s first approximation shell theory and solved by a combination Galerkin Fourier series expansion methods. Equivalent elastic pro...

Thin cylindrical shell structures can show interesting bistable behaviour. If made unstressed from isotropic materials they are only stable in the initial configuration, but if made from fibre-reinforced composites they may also have a second, stable configuration. If the layup of the composite is antisymmetric, this alternative stable configuration forms a tight coil; if the layup is symmetric...
