Abstract: | A two-dimensional mesoscale simulation method based on the natural element method, which is a kind of meshless method, is developed and applied to the analysis of overall elastic moduli, macro yield stress and void-linking fracture. The calculated results are compared with the theoretical solutions for overall elastic moduli, the experimental macro yield stress for aluminum and brass as well as the improved Gurson’s yield function, and the experimental void linking fracture to show the validity of the proposed method. |
