Combining the elastica theory. f.nite element (f.) analy.is, and a geometrical topological experiment, we studied the mechanical behavior of.a ring subjected to multi-pairs of.evenly.distributed equal radial f.rces by.looking at its seven distinct states. The results showed that the theoretical predictions of.the ring def.rmation and strain energy.matched the f. results very.well, and that the ring def.rmations were comparable to the topological experiment. Moreover, no matter whether the ring was compressed or tensioned by.N-pairs of.f.rces, the ring alway. tended to be regular poly.ons with 2N sides as the f.rce increased, and a proper compressive f.rce def.rmed the ring into exquisite f.ower-like patterns. The present study.solves a basic mechanical problem of.a ring subjected to lateral f.rces, which can be usef.l f.r study.ng the relevant mechanical behavior of.ring structures f.om the nano- to the macro-scale.

Electroosmosis has been shown to be an ef.ective means of.dif.erent applications in various f.elds such as Micro-Electro-Mechanical sy.tems （MEMS） and biomimetics applications. This paper aims to prove the concept that the electroosmosis phenomena can also be cooperated into larger scale applications in the building service industry.like dehumidif.cation or damping proof. The electroosmotic f.ow inside a porous medium is validated experimentally.to f.rther understand the dehumidif.cation mechanism of.combined techniques. An experimental test validates that the condensation f.om the porous medium can be obtained by.electroosmotic f.rce generated by.external electric f.eld, especially.f.r specif.c desiccant powders like zeolite and diatomaceous earth. With a range of.volts f.om 5 V to 20 V apply.ng between the testing plates, the maximum f.ow rate through the cross section in the testing plate achieved during the peak period is 1.35 laL＇min 1. These promising phenomena can act as an alternative way.f.r energy.choice in dehumidif.cation industrial f.eld. f.rther researches on new regeneration methods f.r solid desiccant dehumidif.cation are required to make the sy.tem simple, energy.saving and suitable f.r small air conditioning units.

DEGRADATION BEHAVIORS Of.NEW Ty.E TiV-BASED Hy.ROGEN STORAGE ELECTRODE ALLOy.

引用

Acta Metallurgica Sinica(English Letters) 2006年第1期19卷 68-74页

作者： X.Z. Sun y. f. Zhu y. lin R. li M.X. Gao H. G. Pan Department of.Materials Science and Engineering Zhejiang University Hangzhou310027 China

The degradation behaviors of.the TiV-based multiphase hy.rogen storage alloy.Ti0.8Zr0.2V3.2Mn0.64 Cr0.96Ni1.2 during electrochemical cy.ling in alkaline electroly.e have been studied by.XRD, SEM, EIS and AES measurements. XRD analy.is indicates that the alloy.consists of.a C14-ty.e Laves phase and a V-based solid solution. The lattice parameters of.both phases are increased af.er discharged with cy.ling, which indicates that more irreversible hy.rogen remains not discharged in the alloy. It shold be responsible f.r the decrease of.discharge capacity. SEM micrographs show that af.er 10 electrochemical cy.les, a large number of.cracks can be observed in the alloy. existing mainly.in the V-based solid solution phase. Moreover, af.er 30 cy.les, the alloy.particles are obviously.pulverized due to the larger expansion and shrinkage of.cell volumes during hy.rogen absorption and desorption, which induces the f.st degradation of.the TiV-based hy.rogen storage alloy.. EIS and AES measurements indicate that some passive oxide f.lm has been f.rmed on the surf.ce of.alloy.electrode, which has higher charge-transf.r resistance, lower hy.rogen dif.usivity. and less electro-cataly.ic activity. Theref.re it can be concluded that the pulverization and oxidation of.the alloy.are the main f.ctors responsible f.r the f.st degradation of.the TiV-hased hy.rogen storage alloy..

Ef.ect of.electric boundary.conditions on crack propagation in f.rroelectric ceramics

引用

Acta Mechanica Sinica 2014年第2期30卷 153-160页

作者： f.-X. li y.Sun R.K.N.D.Rajapakse State Key.Laboratory.f.r Turbulence and Complex Sy.tems College of EngineeringPeking University f.culty.of.Applied Sciences Simon Fraser University

In this paper, the ef.ect of.electric boundary.conditions on Mode I crack propagation in f.rroelectric ceramics is studied by.using both linear and nonlinear piezoelectric f.acture mechanics. In linear analy.is, impermeable cracks under open circuit and short circuit are analy.ed using the Stroh f.rmalism and a rescaling method. It is shown that the energy.release rate in short circuit is larger than that in open circuit. In nonlinear analy.is, permeable crack conditions are used and the nonlinear ef.ect of.domain switching near a crack tip is considered using an energy.based switching criterion proposed by.Hwang et al.（Acta Metal. Mater.,1995）. In open circuit, a large depolarization f.eld induced by.domain switching makes switching much more dif.cult than that in short circuit. Analy.is shows that the energy.release rate in short circuit is still larger than that in open circuit, and is also larger than the linear result. Consequently.whether using linear or nonlinear f.acture analy.is, a crack is f.und easier to propagate in short circuit than in open circuit, which is consistent with the experimental observations of.Kounga Njiwa et al.（Eng. f.act. Mech., 2006）.

f.ontiers of.Structural and Civil Engineering 2016年第3期10卷 291-302页

作者： Tony.T. y. y.NG y.anjie li International Joint Research Laboratory.of.Eearthquake Engineering 1239 Siping Road Shanghai 200002 China Department of.Civil Engineering University of British Columbia Vancouver BC V6T1Z4 Canada

Buckling restrained knee braced truss moment f.ame （BRKBTMf. is a novel and innovative steel structural sy.tem that utilizes the advantages of.long-span trusses and dedicated structural f.ses f.r seismic applications. Steel trusses are very.economical and ef.ective in spanning large distance. However, conventional steel trusses are ty.ically.not suitable f.r seismic application, due to its lack of.ductility.and poor energy.dissipation capacity. BRKBTMf.utilizes buckling restrained braces （BRBs） as the designated structural f.ses to dissipate the sudden surge of.earthquake energy. This allows the BRKBTMf.to economically.and ef.iciently.create large span structural sy.tems f.r seismic applications. In this paper, a prototy.e BRKBTMf.of.ice building located in Berkeley. Calif.rnia, USA, was designed using perf.rmance-based plastic design procedure. The seismic perf.rmance of.the prototy.e building was assessed using the state-of.the-art f.nite element sof.ware, OpenSees. Detailed BRB hy.teresis and advanced element removal technique was implemented. The modeling approach allows the simulation f.r the f.rce-def.rmation response of.the BRB and the f.rce redistribution within the sy.tem af.er the BRBs f.acture. The developed f.nite element model was analy.ed using incremental dy.amic analy.is approach to quantif. the seismic perf.rmance of.BRKBTMf. The results show BRKBTMf.has excellent seismic perf.rmance with well controlled structural responses and resistance against collapse. In addition, lif. cy.le repair cost of.BRKBTMf.was assessed using the next-generation perf.rmance-based earthquake engineering f.amework. The results conf.rm that BRKBTMf.can ef.ectively.control the structural and non-structural component damages and minimize the repair costs of.the structure under dif.erent ranges of.earthquake shaking intensities. This studies conclude that BRKBTMf.is a viable and ef.ective seismic f.rce resisting sy.tem.

作者： li, N. li, S. Xi, y. Institute of.Automation Shanghai Jiaotong University Shanghai 200030 China

Input-output data f.tting methods are of.en used f.r unknown-structure nonlinear sy.tem modeling. Based on model-on-demand tactics, a multiple model approach to modeling f.r nonlinear sy.tems is presented. The basic idea is to f.nd out, f.om vast historical sy.tem input-output data sets, some data sets matching with the current working point, then to develop a local model using Local Poly.omial f.tting (LPf. algorithm. With the change of.working points, multiple local models are built, which realize the exact modeling f.r the global sy.tem. By.comparing to other methods, the simulation results show good perf.rmance f.r its simple, ef.ective and reliable estimation.
