Numerical Analysis of the Effects of Void Growth and Crack Tip Opening on Ductile Fracture

The ductile rupture of metal alloys depends on the presence of small second phase particles which nucleate microscopic voids. Plastic flow in the metal allows the voids to grow and link up to create larger flaws such as cracks. In previous research, the basic mechanics of ductile fracture has been examined using two-dimensional models. However, some problems in ductile fracture are inherently three-dimensional. In this work three such problems are solved using large deformation finite element computations.
