Nonlinear bending of polygonal functionally graded plates resting on elastic foundation

To investigate nonlinear bending of the functionally graded (FGM) plates with complex shape and resting on elastic foundation a variational-structural method (RFM) is proposed. Mathematical statement boundary value problems plate carried out in framework classical geometrically theory. solve sequence linear obtained as result linearization original system equations by successive loadings Newton method, R-functions was applied. Testing, well comparison results other authors, made it possible to establish reliability effectiveness developed approach apply study stress-strain state (SSS) thin shape. A computational experiment for hexagonal mixed conditions various types external load characteristics. The relationship between greatest deflection obtained. are presented form graphs.
