This research continues and completes a three-dimensional numerical             analysis for ductile rupture and plasticity induced during crack                growth.  Finite element calculations with very fine meshes will be made         for cracks growing under large-scale yielding.  The results will be             compared with near crack stress fields generated during small-scale             yielding.  Specific cases of ductile fracture near blunting crack tips          and the growth of a plane strain crack in large-scale yielding will be          considered.  The three-dimensional numerial analysis results will               provide significant new input to understand the mechanics of ductile            crack growth and will help to develop computer algorithms in metal              forming such as for drawing, rolling, and extrusion.
