Abstract
The Gurson's constitutive model is investigated. Based on the Gurson's constitutive model and large elastic-plastic deformation, the necking behavior of a round tensile bar is analyzed numerically. The void nucleation, growth, hydrostatic tension and material softening in the neck region are discussed. From the numerical results, it is indicated that the development of void and the damage mechanism of material are revealed.
