Accidental events such as collision, grounding, and explosion in marine structures can
cause plastic deformation and structural damage. Various fracture models based on different …

This study deals with ductile fracture prediction of a marine steel using new damage
functions. The stress triaxiality and Lode angle are known to be governing parameters on …

A comparison is made of the ductility limits of one mild (normal) and two high-tensile
strength shipbuilding steels with an emphasis on stress state and loading path dependency …

A phenomenological failure criterion, which attempts to achieve a tradeoff between simplicity
and prediction quality, is developed to predict the fracture behavior of ship structures under …

The initiation of ductile fracture in grade DH36 shipbuilding steel was modeled using the
Hosford-Coulomb fracture model. The hardening and ductile fracture characteristics of DH36 …

This paper aims to present a Continuum Damage Mechanics based fracture model. Two
yield surfaces, plastic and damage, are utilized to develop the model. A modified ductile …

To predict ductile fracture initiation of EH36 grade high tensile strength steels, the Hosford–
Coulomb ductile fracture model was employed. The ductile fracture tests were carried out on …

The predictive capabilities of the Hosford-Coulomb ductile fracture model for shell elements
were evaluated by simulating the penetration of stiffened panel test models. The plasticity …

In this paper, the strain energy density (SED) criterion is proposed for predicting the ductile-
brittle fracture transition (DBFT) in ships and offshore structures. In finite element …

This paper employs a micromechanics framework to investigate the mechanisms and to
predict the ductile fracture of structural steels at intermediate and low-stress triaxialities and …
