Abstract

Abstract

In the present paper, a finite element mined variational functional and the iterative equations of the eccentric orthogonal stiffened plates are developed in accordance with nonlinear elasticity. By using an important technique the coupling coefficients of the two dimensional coupling matrix are resolved into the known input data in the programming which is a three-dimensional coefficient matrix. The nonlinear equations are transformed into the instantaneous linear equations. The linear equations are solved by using the conjugate gradient method, As a result therefore, the calculation is simplified enormously, the precision is improved. and a satisfactory result is obtained.
