WebJul 1, 2024 · Unlike brittle fracture, ductile fracture is associated with hardening or necking phenomena before fracture. Since plastic deformation is permanent and irreversible, a portion of internal energy is dissipated by the inelastic properties, which leads to fracture occurring at relatively large deformation. WebSep 1, 2009 · Ductile fracture proceeds by three stages; namely, void initiation, growth, and coalescence. This process is generally initiated around the inclusions or second phase particles in the material [9], [10], [11]. Therefore, it is reasonable to expect that geometric singularities influence the ductile fracture process.
