Identification of GTN model parameters by application of response surface methodology [PDF]
Procedia Engineering, 2011 A reliable prediction of ductile failure in metals is still a wide-open matter of research. Among different models, Gurson-Tvergaard-Needleman (GTN) has been used extensively.

Modelling of ductile fracture in single point incremental forming using a modified GTN model [PDF]
Engineering Fracture Mechanics, 2017 Understanding the deformation and failure mechanisms in single point incremental forming (SPIF) is of great importance for achieving improved formability.

Ductile fracture prediction of HPDC aluminum alloy based on a shear-modified GTN damage model
Engineering Fracture Mechanics, 2023 In this paper, we investigate how the shear-modified Gurson-Tvergaard-Needleman (GTN) model can be used to reveal the effect of manufacturing-process-induced porosity on the scatter of ductile fracture properties of a high-pressure die-casting aluminum ...

Benchmark Analysis by Beremin Model and GTN Model in CAF Subcommittee
Volume 1: Codes and Standards, 2021Abstract In order to establish a guideline for fracture evaluation without excessive conservatism by considering plastic constraint in the ductile-brittle transition temperature (DBTT) region, the CAF (Constraint-Based Assessment of Fracture in Ductile-Brittle Transition Temperature Region) subcommittee has been launched in 2018 in the ...

AN ANISOTROPIC EXTENSION FOR A THERMOVISCOPLASTIC GTN DUCTILE DAMAGE MODEL
International Journal for Multiscale Computational Engineering, 2023In this work, a thermoviscoplastic GTN ductile damage model is extended to account for anisotropic plastic behavior. The novel feature of the proposed model is the enrichment of a GTN model, with the Hill's yield criterion accounting for hardening, softening, strain-rate effect, plastic work heating, thermal diffusion, and void shearing mechanism.

Micromechanical modelling of weldments using GTN model
International Journal of Fracture, 2010Non-transferability of fracture data from specimen level to component level is a serious limitation of conventional fracture mechanics, as fracture resistance data obtained is largely geometry dependant. The difficulty is largely overcome by GTN model which models the drop in load carrying capacity of a material with the increase in plastic strain ...

No additive effect of combining sumatriptan and olcegepant in the GTN mouse model of migraine
Cephalalgia, 2020Introduction Despite recent advances in migraine treatment there is a need for therapies with higher clinical efficacy and/or fewer side effects. Triptans (5-HT 1B/1D/1F agonists) are essential in the present treatment regime and gepants (CGRP ...

An extended GTN model for indentation-induced damage
Computational Materials Science, 2017Abstract The damage of metallic alloys induced by tensile deformation can be well described by Gurson-Tvergaard-Needleman (GTN) model. However, damage growth under intense shear loading, which has been found in micro-/macro-indentation tests, cannot be captured by this model.

Notched Specimens Fracture Prediction with an Advanced GTN Model
Key Engineering Materials, 2011This present contribution consists of implementing an advanced GTN damage model as a "User Material subroutine" in the Abaqus FE code. This damage model is based on specific nucleation and growth laws in order to predict the void coalescence properties of the material. When applied, this implementation predicts the damage evolution and the stress state
