The present paper deals with a modification of the stress triaxiality-based Lemaitre damage
model to predict the ductile fracture at low stress triaxiality and shear-dominated loadings …

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 …

In this study, the ductile fracture of the alloy metal is analyzed. First, the key factors affecting
the initiation of ductile fracture are investigated. Then, a new uncoupled ductile fracture …

The ductile fracture behaviour of metallic materials is strongly dependent on the material's
stress state and loading history. This paper presents a concept of damage initiation and …

In this paper, an anisotropic failure model proposed by Ganjiani [Ganjiani, M., 2020. A
damage model for predicting ductile fracture with considering the dependency on stress …

The present study details the methodology of the identification process of uncoupled
damage formulations proposed by Bai and Wierzbicki (B&W model–Bai and Wierzbicki …

Dual phase (DP) steels consisting of two phases, ferrite and dispersed martensite, offer an
attractive combination of strength and stretchability, which is a result of the strong …

In this contribution, a numerical assessment of three isotropic constitutive models is
performed in order to identify their applicability and reliability in the prediction of ductile …

Continuous damage accumulation resulting from void nucleation, growth, and coalescence
leads to the final ductile fracture. The Gurson–Tvergaard–Needleman (GTN) model and its …

In the absence of geometrical constraints, ductile fracture has been identified as the
predominant mode of failure for structural elements under extreme loads, the prediction of …
