Abstract Creep response for isotropic axisymmetric rotating disc made of a particle-reinforced FGM has been investigated in the present study. The result obtained for non linear variation of particle distribution along the radial distance of the disc are compared with that of discs containing the same amount of particle distributed uniformly or linearly along the radial distance. The disc under...

Free vibration characteristics of polymer composite plates reinforced by graphene nanosheets employing the Eringen nonlocal elasticity theory were investigated. Theoretical formulations are derived based on Hamilton’s principle implementing linear orthotropic constitutive equations of lamina while the behavior of nanostructure points affected by all other nonlocal points is also taken into acco...

Graphene-reinforced aluminium composites have been widely studied due to their excellent mechanical properties. However, only a few studies reported dynamic compression The purpose of this study is investigate the quasi-static and properties graphene-reinforced composites. addition graphene improved compressive stress resistance energy absorption capacity matrix. An aluminium-0.5 wt.% composite...

this paper deals with local buckling analysis of rectangular functionally graded material plates using finite strip method and based on classical plate theory. the modulus of elasticity of the plate is assumed to vary according to a power-law distribution in terms of the volume fractions of the constituents. the principle of minimum total potential energy is employed to obtain stiffness and sta...

Carbon-based nanomaterials mainly including carbon nanotubes (CNTs), graphene, and graphene oxide (GO) have superior properties of low density, outstanding strength, high hardness. Compared with ceramic reinforcements, small amount carbon-based can significantly improve the mechanical metal matrix composites (MMCs) (CMCs). However, CNTs graphite always aggregate or degrade during fabrication a ...

Robust and stable microcapsules are assembled from poly-amino acid-modified silk fibroin reinforced with graphene oxide flakes using layer-by-layer (LbL) assembly, based on biocompatible natural protein and carbon nanosheets. The composite microcapsules are extremely stable in acidic (pH 2.0) and basic (pH 11.5) conditions, accompanied with pH-triggered permeability, which facilitates the contr...

The production of cement alone is responsible for 5–8% global CO2 emissions. This high environmental footprint can be partly attributed to inefficiencies at the material and structural level in concrete structures. Although performance requirements vary spatially within a element, single with same properties typically used ubiquitously, instead being tailored requirements. leads utilisation emb...

Introducing the differential design concept of functional gradient into mass concrete structures is a feasible that can meet requirement crack resistance and internal hydration heat reduction for in cold regions. This study analyzed functionally graded concrete’s long-term performance durability behavior through experimental tests. Based on various mix proportion designs, six groups were select...
