Application of a shear-modified GTN model to incremental sheet forming
AIP Conference Proceedings, 2013This paper investigates the effects of using a shear-modified Gurson-Tvergaard-Needleman model, which is based on the mechanics of voids, for simulating material behavior in the incremental forming process. The problem chosen for analysis is a simplified version of the NUMISHEET 2014 incremental forming benchmark test.

Application of the GTN model to predict the forming limit diagram of IF-Steel
Journal of Mechanical Science and Technology, 2012Forming limit diagrams (FLDs) are extensively used in industries, particularly the auto industry. The establishment of these diagrams using a predictive approach can lead to reduction in both cost and time. In the present work, Gurson-Tvergaard-Needleman (GTN), a porosity-based model, was used to predict the FLD of an interstitial-free steel via finite

On the Utilization of Shear Modified GTN Damage Model in Cold Rolling
Applied Mechanics and Materials, 2015Edge cracking is a commonly observed phenomenon in cold rolling process, but researchers appear to be far from fully understanding its failure mechanism due to the complex stress conditions of steel strip under the rolling condition. In this research, the shear modified GTN damage model coupled with Nahshon-Hutchinson shear damage mechanism was applied

FEA Simulation of Clinching Process Based on GTN Damage Model
Advanced Materials Research, 2013In this work, the Gurson-Tvergaard-Needleman (GTN) damage model is adopted to depict the material damage during the clinch joining process in a simulation-based theoretical model. The parameters of the GTN model which influence the void nucleation, growth and coalescence are identified.

A Double-Blind Study of SB-220453 (Tonerbasat) in the Glyceryltrinitrate (GTN) Model of Migraine
Cephalalgia, 2004The need for experimental migraine models increases as therapeutic options widen. In the present study, we investigated SB-220453 for efficacy in the glyceryltrinitrate (GTN) human experimental migraine model. SB-220453 is a novel benzopyran compound, which in animal models inhibits neurogenic inflammation, blocks propagation of spreading depression ...
