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 ...
