Ductile fracture for clustered shape matching
Proceedings of the 20th ACM SIGGRAPH Symposium on Interactive 3D Graphics and Games, 2016In this paper, we incorporate ductile fracture into the clustered shape matching simulation framework for deformable bodies, thus filling a gap in the shape matching literature. Our plasticity and fracture models are inspired by the finite element literature on deformable bodies, but are adapted to the clustered shape matching framework.

The key point in this paper is the prediction of the onset of ductile fracture with a newly proposed ductile fracture criterion in various stress state ranging from shear to uniaxial tension. A series of tension tests with different material orientations are carried out up to fracture.

In this chapter, the main characteristics of brittle and ductile fractures, caused by single load application, are described. Each section begins with a description of the macroscopic features that allow for identification of brittle and ductile fractures, and continues with the description of the mechanisms of formation of the fractographic features ...

Abstract Cup-and-cone fracture in single-phase ductile metals appears to originate at holes formed by drawing away of material from non-metallic inclusions, as suggested by Tipper. In copper, the holes expand under the triaxial stresses in the neck and coalesce in a macroscopic fissure; in α iron fine cracks are formed by the stress concentrated at the

On the history of the determination of ductile fracture (ductility) of metals
Journal of Materials Processing Technology, 1997Abstract Some aspects of fracture in metal forming are considered in this paper. (The topic is very extensive, and it is as old as metal forming itself, but the author will limit himself to the consideration of the subject matter, as it is the continuation of the modern theory of plasticity which is no more than a century and a half old.) In addition

Abstract This chapter discusses the causes and effects of ductile and brittle fracture and their key differences. It describes the characteristics of ductile fracture, explaining how microvoids develop and coalesce into larger cavities that are rapidly pulled apart, leaving bowl-shaped voids or dimples on each side of the fracture ...
