Following the discovery of Higgs boson at LHC, new large colliders are being studied by international high-energy community to explore physics in detail and beyond Standard Model. In China, a two-stage circular collider project CEPC-SPPC is proposed, with first stage CEPC (Circular Electron Positron Collier, so-called factory) focused on physics, second SPPC (Super Proton-Proton Collider) This paper discusses this stage.
This paper presents the goal and status of high field High Temperature Superconductor (HTS) solenoid program funded through a series SBIRs. The target this R&D is to build HTS coils that are capable producing fields greater than 20 T when tested alone approaching 40 in background magnet. will be made with second generation (2G) engineering current density tape. To date, 17 pancake have been built temperature range from K 80 K. Quench protection, stresses minimization degradation conductor...
Abstract This work presents the numerical analysis of natural fiber reinforced composites (from renewable sources), to evaluate mechanical behavior Bio-composites and elucidated role micro-mechanical analytical models (Rule Mixtures Halpin-Tsai models). Specifically, this study is carried out perform Multi-scale modeling simulation Biocomposite that constitute sisal reinforcement Epoxidized Soybean-Oil (ESO) based matrix. In general, it difficult predict effective properties due its...
The present study deals with the fabrication of hybrid composites using biodegradable and ecologically friendly natural fibers a recyclable thermoplastic matrix. Pure fiber high-density polyethylene (HDPE) Kenaf Ramie fiber, 20 wt%, were fabricated microwave-assisted compression molding. composite's mechanical characterization was performed tensile, flexural, impact, hardness tests. X-ray diffraction done to investigate crystallinity percentage, scanning electron microscopy fractured...
Multistable laminates have attracted the attention of researchers for developing morphing structures, as they can stay in different stable configurations without any need external forces to maintain those configurations. In this study, a novel application reconfigurable antenna made with rectangular composite [90/0] shape star is analyzed using Variational Asymptotic Method (VAM), which free ad-hoc assumptions and highly accurate, unlike semi-analytical theories present literature. The...
The overuse of fossil fuels has polluted the ecosystem. Hydrogen as a fuel is an excellent alternative because sole by-product water, making it clean fuel. ultra-light gas and therefore occupies substantial volume at atmospheric pressure. It stored extremely high pressures to reduce required for storage. Since storage hydrogen necessitates pressure (working 700 bar), vessels that resist such are constructed from composite materials with outstanding mechanical properties. Type IV best...
In recent times natural fibers are getting major attention from researchers and industries to optimize the use of these fibers, especially with combination polymers as a composite structure, due environmental awareness. Furthermore, it shows few advantages, such biodegradability, lightweight, non-toxic characteristics. this work, multiple samples Microwave cured fiber composites made. The act reinforcements in polymer-based resin matrix. used work Kenaf Ramie fibers. High-density...
In this paper, an outline of mean-field homogenization and fracture toughness boron nitride nanotube-reinforced aluminium epoxy composites have been presented. The meso-scale material modelling has achieved using Mori-Tanaka double inclusion schemes. To examine the effectiveness schemes, a comparison drawn with rule mixture. Meso-scale numerical results are presented for various design parameters such as aspect ratio volume fraction nanotubes. validation studies developed transversely...
In this work, a three-dimensional thermomechanical finite element model has been developed to simulate the additive manufacturing process of Ti-6Al-4V hip implant fabricated using laser powder bed fusion process. The numerical is used predict thermal fields, residual stresses, and part deformation during printing To reduce mass consequently weight implant, topology optimization carried out. Furthermore, additively manufactured subjected realistic loading conditions analyzed. model, new...
This work aims to develop an asymptotically accurate 2D nonlinear constitutive relation between stress resultants and strain tensors for the compressible anisotropic hyperelastic material using Variational Asymptotic Method (VAM). Geometric nonlinearity is allowed by virtue of finite displacements rotations, while through generalized Fung model. The geometric small parameter (the ratio thickness characteristic dimension far less than 1), physical (maximum allowable up 20 percent), categorize...
