The buckling of a cross-ply laminated non-homogeneous orthotropic composite cylindrical thin shell under time dependent external pressure
A.H. Sofiyev

Abstract     [Full Text]
    The subject of this investigation is to study the buckling of cross-ply laminated orthotropic cylindrical thin shells with variable elasticity moduli and densities in the thickness direction, under external pressure, which is a power function of time. The dynamic stability and compatibility equations are obtained first. These equations are subsequently reduced to a system of time dependent differential
equations with variable coefficients by using Galerkin
Key Words
    buckling; non-homogeneous; cross-ply laminated; orthotropic shell; external pressure; dynamic critical load; dynamic factor; critical impulse; wave number.
