A Three Dimensional Model for Nanocrystalline Materials based on Grain Interior and Grain Boundary Deformation Mechanisms
Gürses, Ercan (null; 2013-09-05)
Nanocrystalline metals, because of their distinct features, e.g., high strength, low ductility, pronounced rate dependence, tension-compression asymmetry and susceptibility to plastic instability, has become the subject of intense research over the past two decades. Owing to a large volume fraction of grain boundary (GB) atoms, the deformation mechanisms in nanocrystalline metals are different from traditional coarse-grained polycrystals. Indeed, there are several inelastic deformation mechanisms, e.g., GB-...

A Finite element model for partially restrained steel beam to column connections
Köseoğlu, Ahmet; Sarıtaş, Afşin; Department of Civil Engineering (2013)
In the analyses of steel framed structures it is customary to assume the beam to column connections as either fully rigid which means that all moments are transferred from beam to column with negligible rotation or ideally pinned that resists negligible moment. This assumption is reasonable for some types of connections. However when considering steel connections such as bolted-bolted double web angle connections it can be seen that the behavior of these connections is in between the two extreme cases. Thus...
A phase-field model for fracture of unidirectional fiber-reinforced polymer matrix composites
Denli, Funda Aksu; Gultekin, Osman; Holzapfel, Gerhard A.; Dal, Hüsnü (Springer Science and Business Media LLC, 2020-04-01)
This study presents a crack phase-field approach for anisotropic continua to model, in particular, fracture of fiber-reinforced matrix composites. Starting with the variational formulation of the multi-field problem of fracture in terms of the deformation and the crack phase fields, the governing equations feature the evolution of the anisotropic crack phase-field and the balance of linear momentum, presented for finite and small strains. A recently proposed energy-based anisotropic failure criterion is inc...
