Based on the classical shell theory, the linear dynamic response of functionally graded carbon nanotube-reinforced composite (FG-CNTRC) truncated conical shells resting on elastic foundations subjected to dynamic loads is presented. The truncated conical shells are reinforced by single-walled carbon nanotubes (SWCNTs) that vary according to the linear functions of the shell thickness. The motio...

In this paper the energy absorption capacity of stiffened circular composite tube is considered. The governing equations and dynamic equilibrium are first derived and then solved. Additionally, a finite element model of reinforced circular composite tube structure is modeled. At the following, the effects of various parameters such as structural geometry, number of rings and stingers on mechani...

Given an embedded cylinder in an arbitrary surface, we give a gauge theoretic definition of the associated Goldman flow, which is a circle action on a dense open subset of the moduli space of equivalence classes of flat SU(2)-connections over the surface. A cylinder in a compact nonorientable surface lifts to two cylinders in the orientable double cover, and the composite flow is the compositio...

Na–CO2 batteries recently are emerging as promising energy-storage devices due to the abundance of Na in earth's crust and clean utilization greenhouse gas CO2. However, similar metallic Li, also suffers from a serious issue dendrite growth upon repeated cycling, while facile method solve this is still lacking. In work, we report an effective, environmentally friendly inhibit by situ constructi...

This study indicates the analysis of functionally graded carbon nanotube reinforced composite (FG-CNTRC) plates using a four-node quadrilateral element related to C0-type Reddy’s third-order shear deformation theory (C0 HSDT) and cell-based smoothed strains (CS) strategy. is surely taking advantages desirable properties theory. Besides, FG-CNTRC with advanced material are changed from bottom to...

Finely dispersed sandwich composite nanoparticles of Cu–Ni–Cu were prepared by a novel method combining template synthesis and an ultrasonic treatment method. The composite nanoparticles have uniform cylinder shape with tunable diameter and length. Transmission electron microscopy (TEM) and electron diffraction (ED) were employed to characterize the nanoparticles. This method can be used to fab...

After undergoing a manufacturing process, materials may exhibit internal stresses referred to as residual stresses. In steel-composite hybrid structures, residual stresses are typically formed due to the unequal thermal behaviour of the steel and composite. Thus, knowledge of the residual stress state is important in the assessment of the external-internal loading in steel-composite hybrid stru...
