This paper presents the Hencky bar-chain model (HBM) for buckling and vibration analyses of Euler–Bernoulli beams with elastic end restraints. The comprises rigid beam segments (of length a = L/n where L is total n number segments) connected by frictionless hinges rotational springs stiffness EI/a EI flexural rigidity beam. elasticity mass are concentrated at springs. key contribution this lies in modeling restraints that will simulate same results as furnished first-order central finite...
AimsAtrial fibrillation (AF), the commonest cardiac arrhythmia, has been strongly linked with arrhythmogenic sources near pulmonary veins (PVs), but underlying mechanisms are not fully understood.We aim to study generation and sustenance of wave in a model PV tissue. Methods resultsA previously developed biophysically detailed three-dimensional canine atrial is applied.Effects AF-induced electrical remodelling introduced based on published experimental data, as changes ion channel currents...
This paper presented new analytical solutions for the elastic buckling of Eringen’s nonlocal columns with allowance selfweight. A discrete column model on basis central finite difference formulation and equivalent Hencky bar-chain also were this problem. The allows one to determine constructed from repetitive cells. In addition, may use calibrate small-length scale coefficient e0 in model. It was found that values varied 0.289 0.373 respect increasing selfweight clamped-free case, 0.276...
This article demonstrates the design potentials of a recently developed approach for generating smooth poly-hypar surfaces, freeform surfaces made combinations hyperbolic paraboloids (hypars). In surface, double curvature individual hypar modules and connections between them ensure global bending-free structural behaviour. this article, analysis prestressed gridshell as surface is introduced. Graphic statics used to evaluate control distribution internal forces within structure. Moreover,...
In this paper, a synthesised performance analysis with modal parameters (SPAMP) method is proposed to solve vibration problems of railway vehicle. With the SPAMP method, relations between parameters, physical and ride quality are built at first unified 'track–vehicle–human' model. Then they used experimentally identified response power spectral densities find ways improve quality. Using low-frequency problem kind speed-up vehicle in China researched. It was found that mainly caused by lower...
This paper is concerned with the development of Hencky bar-net model (HBM) for free vibration analyses rectangular plates mixed boundary conditions and point supports. The HBM a two-dimensional discrete net system composed rigid segments connected by frictionless hinges rotational springs. In model, bending accommodated springs at each joint while twisting diagonal spring in grid cell. total mass plate distributed as lumped continuous stiffness simulated located edge joints. Owing to...
Orthotopic liver transplantation as treatment for hereditary enzyme deficiences in the absence of cirrhosis suffers from significant operative risks, complications, and donor shortages. Transplantation isolated hepatocytes (HTX) may offer opportunities these diseases retain recipient liver. Hepatocytes transplanted into portal vein, spleen, or omentum lack ideal growing environment cell proliferation maintenance. Therefore, we investigated a method combining 75% hepatectomy with direct...
A hierarchically designed Al-5083 composite achieves dramatic mechanical properties at impact rates of deformation through a combination three micro-structural length scales: strengthening nanocrystalline core architecture and length-scale dependent reinforcement with μ-sized ceramic particles, enhanced ductility the incorporation certain volume fraction microscale grains (see fig.).
