摘要

This paper represents nonlinear analysis of rhombic sandwich plates with orthotropic core under uniform load. Banerjee 's hypothesis [1] involving a new form of energy expression in the total potential energy of the system has been employed. As a consequence the differential equation is decoupled keeping intact its nonlinear character. The aim of the present study is to analyze the nonlinear behaviour of rhombic sandwich plates with orthotropic core under uniform load for different skew angles. The results have been obtained both for movable and immovable edges from a single cubic equation. Numerical results (central deflection vs. load) have been computed and compared with known results for square sandwich plates only. Results for different skew angles are believed to be new.
