Abstract:

In finite element method the Total-Lagrangian (T. L) and Updated-Lagrangian (U. L) formulations are usually based on the displacement method. In this paper approximate equations are formulated by using the generalized strain method developed by professor Chen Baiping. The larg-e deflection analysis of clamped and simply supported rectangular and square plates under uniform load has been calculated by the above approach. The numerical results are compared favorably with other known solutions and experimental results.

Key words: generalized strain method, large deflection, plates
