A Comparison of Shear Mechanisms for the Prediction of Ductile Failure under Lo...
F. J. P. Reis; L. Malcher; F. M. Andrade Pires; J. M. A. César de SáPurpose - The purpose of this paper is to perform a numerical assessment of two recently proposed extensions of the Gurson-Tveegard-Needleman ductile damage constitutive model under low stress triaxiality. Design/methodology/ approach - One of the most widely used ductile damage models is the so-called Gurson-Tveegard-Needleman model, commonly known as GTN model. The GTN model has embedded into its damage formu...
