| Abstract: | In this paper the meshless natural method(MNNM) is applied to solve elasto-plastic problems and the governing equation is achieved too.2D elasto-plastic large deformation program has been worked out.Finally distortion result of strip foundation is accomplished to test and verify the theory and program.The comparison of the calculated results with those obtained using finite elements method shows that the proposed methods can solve large deformation problems of elasto-plastic material well. |
