In order to make natural element method (NEM) be applied to calculate and analyse the elastoplastic material, through cosidering the essential elasto-plastic theory and the specialties of NEM, an algorithm for two dimensional elasto-plastic analysis based on the yield criteria of Von-Mises, Mohr-Coulomb and Drucker-Prager was presented. Each of them has an example to check its exactness and proves its advantage at precision. Those works enlarged the applicable range of NEM.

Key words: natural element method (NEM), elasto-plastic analysis, Delaunay triangulation, yield criteria
