Formability prediction using bifurcation criteria and GTN damage model [PDF]
International Journal of Mechanical Sciences, 2021 In this paper, four plastic instability criteria, which are based on the bifurcation theory, are coupled with the GTN damage model for the prediction of diffuse and localized necking. General bifurcation (GB) criterion and limit-point bifurcation (LPB) criterion are used to predict diffuse necking, while loss of ellipticity (LOE) criterion and loss of ...

A GTN-like Model for Plastic Porous Materials
Engineering, Technology & Applied Science Research, 2014 An extended version of the well-known Gurson-Tvergaard-Needleman (GTN) isotropic hardening model is presented in this paper. The yield function of the proposed constitutive model possesses the distinctiveness to explicitly depend upon the third stress invariant. The presented constitutive model is used to analyze the necking of a round tensile bar.

Limit shape and height fluctuations of random perfect matchings on square-hexagon lattices [PDF]
, 2020 We study asymptotics of perfect matchings on a large class of graphs called the contracting square-hexagon lattice, which is constructed row by row from either a row of a square grid or a row of a hexagonal lattice.
