A nano-scale material model applied in finite element analysis of aluminium plates under impact loading
(Journal article, 2013)Finite element simulations of AA6070 aluminium plates struck by ogival-nose projectiles are performed. The aluminium plates are 20 mm thick and heat treated to temper O, T4, T6 and T7. A nano-scale material model, consisting ... -
Ab-initio study of atomic structure and mechanical behaviour of Al / Fe intermetallic interfaces
(Journal article; Peer reviewed, 2020)First-principles virtual tensile and shear test calculations have been performed to Al(0 0 )//-AlFeSi(0 0 1) and Al(0 4)//Fe4Al13(1 0 ) interfaces by the ab initio pseudo potential density functional theory method. Work ... -
Ductile mechanisms of metals containing pre-existing nanovoids
(Journal article; Peer reviewed, 2016)The void growth in monocrystalline Cu and Fe are investigated by molecular dynamics simulations to reveal the ductile mechanisms based on dislocation emission and propagation. The results show that the void growth in Cu ... -
First principle calculations of pressure dependent yielding in solute strengthened aluminium alloys
(Journal article; Peer reviewed, 2020)The pressure dependence of the yield stress in solute strengthened aluminium alloys is investigated by first principle calculations. The solute elements studied are magnesium, silicon and copper. A fixed boundary cluster ... -
First-principles study of tensile and shear strength of Fe-Al and α-AlFeSi intermetallic compound interfaces
(Peer reviewed; Journal article, 2021)First-principles virtual tensile and shear strength calculations have been performed on the Fe2Al5// Fe4Al13 and -AlFeSi// Fe4Al13 interfaces. The Fast Inertial Relaxation Engine (FIRE) algorithm is used for optimizing ... -
Fracture and negative Poisson’s ratio of novel spanned-fullerenes nanotube networks under tension
(Journal article; Peer reviewed, 2013)Carbon-based nanomaterials have attracted significant attention due to their unique physical properties. In this study, various multi-dimensional graphitic architectures are constructed by spanning fullerenes with carbon ... -
Modeling of textured aluminum alloys used in a bumper system: Material tests and characterization
(Journal article; Peer reviewed, 2006)The three materials AA7108, AA7003 and AA6060, which can be parts of a typical bumper system in aluminum, were characterized in the present paper. Different tempers of the materials were studied. Through simple material ...
