Experimental characterization and numerical modeling of micromechanical damage under different stress states [PDF]
, 2013 The use of HSLA steels for the manufacture of automotive components is interesting from an engineering point of view. This family of steels, while possessing high strength, also has good formability and can be used in forming manufacturing processes.

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 ...

High Temperature Materials and Processes, 2021 Understanding the damage evolution of alloys during a plastic deformation process is significant to the structural design of components and accident prevention. In order to visualize the damage evolution in the plastic deformation of Ti–3Al–2Mo–2Zr alloy,

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.

Journal of Materials Research and Technology, 2023 The damage evolution of TA15 titanium alloy laser-welded joint during hot deformation was studied by tensile tests and the GTN model. Tensile tests of the welded joint at 900 °C with different strain rates were carried out, and the evolution of cracks ...
