THE DEDUCTION OF GOVERNING DIFFERENTIAL EQUATIONS FOR MODERATELY THICK RECTANGULAR PLATES WITH FOUR FREE EDGES
Bending theory of flat plate with extensive four- displacement is put forward and the governing differential equations are accurately derived from moderately thick rectangular plates with four free edges on the elastic foundation of two-parameter by means of variational method, considering transverse extension and contraction displacement Ф<,3> for the first time. The number of boundary conditions is four because of the increased numbers of extensive displacements. The theory which is advanced by the paper can solve most of problems with concentrated loads or stress concentration much better than bending theory of flat plate with extensive three-displacement and it can calculate the error of it. Bending theory of flat plate is widened in the paper.
