Ductile failure analysis of high strength steel in hot forming based on micromechanical damage model
MATEC Web of Conferences, 2016 The damage evolution of high strength steel at elevated temperature is investigated by using the Gurson-Tvergaard-Needleman (GTN) model. A hybrid method integrated thermal tensile test and numerical technique is employed to identify the damage parameters.

Forming limit diagram prediction of 6061 aluminum by GTN damage model [PDF]
Mechanics & Industry, 2018 Forming limit diagram (FLD) is one of the formability criteria which is a plot of major strain versus minor strain. In the present study, Gurson-Tvergaard-Needleman (GTN) model is used for FLD prediction of aluminum alloy 6061. Whereas correct selection of GTN parameters’ is effective in the accuracy of this model, anti-inference method and numerical ...
