| A geometrically nonlinear one dimensional theory of delaminated composite beam/plates, with an initial imperfection under arbitrary axial and transverse loadings for any 2-D boundary conditions, is developed including the effect of transverse shear deformation. The theory is based on a first order Mindlin-Timoshenko type kinematic model with the nonlinear differential equations solved by reducing the equations to a linear sequence and subsequently using a finite difference scheme. A parametric study was carried out to determine the effect of transverse shear deformation on the postbuckling behavior. |
