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 ...
Exhaust gas analysis of an eight cylinder gasoline engine based on engine speed
(Elsevier Ltd, 2017)
In this experimental work, exhaust gas analysis of an eight cylinder and v-type gasoline engine, namely, a Chevrolet 5.7, is experimentally performed in terms of engine speed at laboratory conditions by using of an exhaust ...
Design of hybrid composites from scrap aluminum reinforced with (SiC+TiO2+Gr+Ti+B)
(Springer New York LLC, 2017)
Hybrid Metal Matrix Composites (HMMCs) have very light weight, high strength, and show better resistance to corrosion, oxidation, and wear. Impact resistance is an especially important property of these HMMCs which is ...
