Failure analysis of graphene sheets with multiple Stone-Thrower-Wales defects using molecular mechanics based nonlinear finite element models
(Hitit Üniversitesi Fen Bilimleri Enstitüsü, 2018-06-09)
Experimental studies show that Stone-Thrower-Wales (STW) defects generally exist in graphene sheets (GSs) and these defects considerably affect the fracture strength of GSs. Thus, prediction of failure modes of GSs with ...
Predicting energy absorption parameters of aluminum lattice structures filled tubes via artificial neural networks
(2019)
In this paper, the energy absorption parameters of aluminum body centered cubic lattice structures filled thin-walled tubes under axial loading are predicted via artificial neural networks (ANNs). Different tube thickness, ...
