NONLINEAR STATIC AND DYNAMIC ANALYSIS OF STIFFENED LAMINATED PLATES

The static and dynamic analysis of eccentrically stiffened laminated p lates is presented. For large deformations, the von Karman kinematic r elations of the plate and stiffener are considered in the formulation. Also, the formulation accounts for transverse shear deformation effec ts of the plate and stiffener, and the model is applicable for the ana lysis of both thin and thick stiffened laminated plates, The finite el ement model consists of representing the plate by nine-noded isoparame tric quadrilateral elements and the stiffener by three-noded isoparame tric beam elements. Numerical examples are presented for the non-linea r responses of stiffened laminated plates. The influences of stiffener s such as depth, number, and location are examined.
