Abstract

Postbuckling behavior is investigated for Rectangular Reissner's moderately thick plates and sandwich plates. The fundamental equations and boundary conditions are expressed in unified dimensionless form for rectangular moderately thick plates and sandwich plates. Exact solutions of series form with a number of different boundary conditions, especially with unsymmetrical boundary conditions, are obtained by developing a new technique of mixed Fourier series in nonlinear analysis. The nonlinear partial differential equations are reduced to an infinite set of simultaneous nonlinear algebraic equations, which are truncated by iteration in numerical computations.
