Application of refined theory in the nonlinear analysis of composite laminated structures

A``sandwich'' panel under axial compressive loading is studied over its post-buckling range. Alternative formulations were developed to cover solutions other than the de¯ection shape given by the classical Rayleigh-Ritz analysis. General elasticity principles are used to derive the total potential energy function in terms of the displacement ®eld. Given a constant modal amplitude displacement ®eld, which is introduced in the total potential energy function, the results are discussed having as background models studied earlier. Techniques for the analysis of localized solutions are presented with reference to the study of the beam on nonlinear elastic foundation. The concepts of localization are introduced by using dynamical analogy and the double scale perturbation method and applied to the sandwich panel, to derive the governing amplitude modulation equations. The resulting formulations are discussed using some examples, and by solving analytical and numerically the amplitude differential equations.

This bibliography provides a list of literature references on finite element analysis of basic structural elements. Presented listings contain papers published in scientific journals, conference proceedings, and theses/dissertations retrospectively to 1992. References have been retrieved from the author's database, MAKEBASE. They are grouped into the same sections as described in the first part of this paper, and sorted alphabetically according to the first author's name. In some cases, if a specific paper is relevant for several subject categories, the same reference is listed under respective section headings.Subjects not included in this bibliography: fracture mechanics problems; contact problems; thermal problems. References dealing with developments of various finite elements, stability problems and those analysing composite and concrete structures are included. Beams, columns, rods and bars (BEA)
