| Abstract: | In this paper, the perturbation and finite element method are used to analyse the elastic-plastic problem of incremental theory and the associated flow rule and Drucker-Prager yield function are used to establish the constitutive relation. Then the basic equation of perturbation and finite element method is derived. Through the calculation of a practical example, this method shows good result. |
