【Abstract】 An approximate method for solving the non linear displacement of orthotropic plates and shells has been apllied so far.This method can’t obtain precise solution and its solving process is havey and complicated.An Analytic numerical method for solving rectanyular plates and shells with large deflection displacement is presented and a solution for four sides fixed supported shallow shell is summed up.Calculation exercises show that this method is very efficient to solve the guestion of the plates and shells with large displacement.更多还原
