LARGE DEFLECTION ANALYSIS BY PERTURBATION METHOD USING SYMBOLIC MANIPULATION SYSTEM REDUCE

A perturbation procedure for large deflection analysis is presented as an application of a symbolic manipulation system to structural mechanics. the calculated results are compared with the behaviours obtained by finite element method. The accuracy of solutions by perturbation method is discussed considering the relation between the number of terms and the quantity of deflection. The main conclusions are that a symbolic manipulation system makes it possible to present the nonlinear behaviour of a thin plate in an equation. This characteristic is an advantage of symbolic manipulation to finite element method which needs incremental calculation. In case of large deflection analysis by perturbation method, considerations must be taken as to the applicable range of the solution.
