| Abstract: | The layered approach was adopted to study the numerical procedure of the large deflection of an elastic_plastic Timoshenko's beam,and the nonlinear equilibrium equation was derived by TL Formula. The solution was conducted by means of mNR method. The tangential stiffness matrix of the beam was introduced, and the solving procedures were presented in detail. The solution of the problem is satisfactory. |
