“…6(b-d)), several cavities and voids are obvious which are responsible for reduced fracture strain of composites. These cavities and micro cracks were produced during tensile loading because of low bonding between ceramic reinforcements and Mg-3Al-1Zn alloy matrix [44,45]. The tensile fracture analysis of as-extruded composites is consistent with tensile fracture strain values as shown in Fig.…”

“…The desired properties are achieved by a careful selection of the size and the kind of the reinforcement particles. The reinforced materials mainly used are SiC (silicon carbide), TiC (titanium carbide), Al 2 O 3 (aluminum oxide), B 4 C (boron carbide), CNTs (carbon nano-tubes), and the new graphene nano-platelets (GNPs) [9][10][11]. Rashad et al [9] succeeded in producing magnesium GNPs composites (Mg/0.3wt%GNPs) through a semi-powder metallurgy process.…”

Abstract:The machinability of graphene-reinforced magnesium-based hybrid nanocomposites produced through the application of powder metallurgy method has not been completely reported. This article presents an experimental investigation on the thrust force, the surface roughness (R a ), and drilled surfaces characteristics in the drilling process of a Mg/SiC/GNPs (magnesium matrix based silicon carbide and graphene nanoplatelets) hybrid magnesium matrix composite. The hybrid composite material was produced through the application of a powder metallurgy method. The experiments were carried out with uncoated, PVD (Physical Vapor Deposition), and CVD (Chemical Vapor Deposition) coated tungsten carbide drill bits at three levels of cutting speeds (30, 40, and 50 m/min), and three different levels of feed rate (0.10, 0.15, and 0.20 mm/rev) under dry machining conditions. Taguchi's L 27 (3 3 ) orthogonal array and S/N ratio were used to optimize the optimal parameters for thrust force and surface roughness. The experimental results indicated that the thrust force and the surface roughness were extremely dependent on a particular type of drill bits, feed rate, and cutting speed. The feed rate parameter is known to have a significant influence on the surface finish.

“…Rashad et al [18] investigated the effect of adding graphene nanoplatelets on the mechanical properties of a titanium alloy. According to the results of the microstructural characterization achieved, they concluded that the reinforcement graphene particles were uniformly distributed in the matrix, thus acting as an effective reinforcing filler to prevent the deformation.…”

Sandwich structures are able to provide enhanced strength, stiffness, and lightweight characteristics, thus contributing to an improved overall structural response. To this sandwich configuration one may associate through-thickness graded core material properties and homogeneous or graded properties nanocomposite skins. These tailor-made possibilities may provide alternative design solutions to specific problem requisites. This work aims to address these possibilities, considering to this purpose a package of three beam layerwise models based on different shear deformation theories, implemented through Kriging-based finite elements. The viscoelastic behaviour of the sandwich core is modelled using the complex method and the dynamic problem is solved in the frequency domain. A set of case studies illustrates the performance of the models.
