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 …

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

A study of the damage evolution laws for ductile materials was carried out to predict the
ductile fracture behavior of a marine structural steel (EH36). We conducted proportional and …

It is important to obtain reasonable predictions of the extent of the damage during maritime
accidents such as ship collisions and groundings. Many fracture models based on different …

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 …

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 …

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 …

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 …

A Hosford-Coulomb type ductile fracture surface was developed for DH36 grade steels. The
fracture experiments reported in the literature, which consist of tests with notched tensile …

Coupled experimental and numerical analyses have been carried out to assess and validate
the ductile damage parameter for fracture prediction in Mod. 9Cr–1Mo steel. Tensile tests …
