In this paper, we describe a method for realistically animating
ductile fracture in common solid materials such as plastics and
metals. The effects that characterize ductile fracture occur due to
interaction between plastic yielding and the fracture process. By
modeling this interaction, our ductile fracture method can generate
realistic motion for a much wider range of materials than could be
realized with a purely brittle model. This method directly extends
our prior work on brittle fracture [O'Brien and Hodgins, SIGGRAPH 99].
We show that adapting that method to ductile as well as brittle
materials requires only a simple to implement modification that is
computationally inexpensive. This paper describes this modification
and presents results demonstrating some of the effects that may be
realized with it.
