Description
Summary:The purpose of this paper is to review ductile fracture of metallic systems. The goal has been to present both mechanics and microstructural aspects of ductile fracture and to emphasize the interplay between the approaches. The paper considers first experimental studies and efforts to model the three stages of ductile fracture: void nucleation, void growth and void coalescence. To make explicit the necessity of incorporating both mechanics and microstructure in studies of ductile fracture, the fracture behavior of three different mechanical tests are discussed. These are axisymmetric tensile specimens with and without notches, plane strain tensile specimens and specimens containing sharp notches used to measure fracture initiation toughness.
