Effect of Ductile Damage Evolution in Sheet Metal Forming: Experimental and Numerical Investigations [PDF]
, 2010 The numerical simulation based on the Finite Element Method (FEM) is widely used in academic institutes and in the industry. It is a useful tool to predict many phenomena present in the classical manufacturing forming processes such as necking, fracture,

Ductile damage modelling with locking‐free regularised GTN model
International Journal for Numerical Methods in Engineering, 2018 SummaryThe major goal of this work is to develop a robust modelling strategy for the simulation of ductile damage development including crack initiation and subsequent propagation. For that purpose, a Gurson‐type model is used. This model class, as many other damage models, leads to significant material softening and must be used within a large ...

Hardening effects on strain localization predictions in porous ductile materials using the bifurcation approach [PDF]
, 2015 The localization of deformation into planar bands is often considered as the ultimate stage of strain prior to ductile fracture. In this study, ductility limits of metallic materials are predicted using the Gurson–Tvergaard–Needleman (GTN) damage model ...

Prostaglandin-E2 levels over the course of glyceryl trinitrate provoked migraine attacks
Neurobiology of Pain, 2023 Administration of glyceryl trinitrate (GTN), a donor of nitric oxide, can induce migraine-like attacks in subjects with migraine. Provocation with GTN typically follows a biphasic pattern; it induces immediate headache in subjects with migraine, as well ...

Implementation of GTN Model in Dual-horizon Peridynamics
Procedia Engineering, 2017 In this paper we present a dual-horizon peridynamics (DH-PD) for ductile fracture. The dual-horizon non-ordinary state-based PD is derived based on variational calculus and accounts for large deformation. The GTN model is employed to model the bulk behavior while DH-PD can naturally capture the transition from continuum to discontinuum.
