## Abstract A simple mixed finite element method is developed. The finite element is a rectangular triangle and rectangle. In the element the deflections are assumed to be simple fourβelement polynomials, bending moments, __M__~__x__~ and __M__~__y__~ with a partially linear distribution, and a con
The main purpose of the present work is to formulate a theory that can describe the influence of any initial geometric imperfection on the resonance frequencies of in-plane loaded rectangular plates of any boundary conditions and aspect ratio. The results indicate that the presence of imperfections
A new Navier-type three-dimensionally exact solution for small deΒ―ections in bending of linear elastic isotropic homogeneous rectangular plates of constant thickness is presented. In this solution the transversal normal stresses identically vanish, and the loading is a volume force with a distributi
