Abstract

A seminumerical-semianalytical method is presented for the analysis of rectangular plates with rigidities and subjected to in-plane loads. The procedure is based on the classical method of separation of variables. The two-dimensional governing partial differential equation is first reduced to an ordinary differential equation. Then, the classical unidirectional finite difference technique is used to solve the ordinary different equation. The problem is then reduced to a typical eigenvalue problem which, on solution, yields the buckling coefficient of the plate. Results are presented for plates with different edge and loading conditions.
