Calibration Procedures for a Computational Model of Ductile Fracture
(Elsevier, 2010)A recent extension of the Gurson constitutive model of damage and failure of ductile structural alloys accounts for localization and crack formation under shearing as well as tension. When properly calibrated against a ... -
Simulations of Ductile Fracture in an Idealized Ship Grounding Scenario Using Phenomenological Damage and Cohesive Zone Models
(Elsevier, 2013)Two complementary simulation methodologies for ductile fracture in large sheet metal components are presented and evaluated in this paper. The first approach is based on the phenomenological dilatational plasticity-damage ... -
Tension–Torsion Fracture Experiments – Part II: Simulations with the Extended Gurson Model and a Ductile Fracture Criterion Based on Plastic Strain
(Elsevier, 2013)An extension of the Gurson model that incorporates damage development in shear is used to simulate the tension-torsion test fracture data presented in Faleskog and Barsoum (2012) (Part I) for two steels, Weldox 420 and ...
