Non-Linear Static and Dynamic Analysis of Stiffened Laminated Plates
The static and dynamic analysis of eccentrically stiffened laminated plates is presented. For large deformations, the von Karman kinematic relations of the plate and stiffener are considered in the formulation. Also, the formulation accounts for transverse shear deformation effects of the plate and stiffener, and the model is applicable for the analysis of both thin and thick stiffened laminated plates. The finite element model consists of representing the plate by nine-noded isoparametric quadrilateral elements and the stiffener by three-noded isoparametric beam elements. Numerical examples are presented for the non-linear responses of stiffened laminated plates. The influences of stiffeners such as depth, number, and location are examined.
