D., Kobe University, Graduate School of Science and Technology. Field of study: Molecular Dynamics simulation, Solid Mechanics.We can discuss deformation mechanisms in nanometre-scale materials by computer experiment. This figure shows torsional or bending deformation analysis of a defective carbon nanotube.Solid Mechanics on Nanometre-scale Materials using Atomic SimulationsComputation-simulations reveal complex changes of atomic structure in materials. This figure shows distributions of atomic strain under the indentation simulation on bulk metallic glasses.Graduatesareworkinginbroadfieldssuchasautoandelectronicsindustries.Inthislaboratory,studentsacquirethecomputation-simulationskillandtheknowledgeinsolidmaterials,whichwillbeveryusefulinyourfuturejobs.NishimuraLabIn the FutureMechanical Systems EngineeringAfter Graduation(a) Depth = 2nm(b) Depth = 4nm(c) Depth = 5nm50nmAtomic strain, γ 0.0 0.510nm14.413.415.4Atomic shear stress [GPa]0-5050Lattice defectAtIkedalab,wearedevelopingacontrolmethodtooperatemechanicalsystemssuchassatellitesandautomobilessafelyandaccurately.Inrecentyears,we’vedevelopedmethodstoactivelycontrolsteeringinordertoimprovethesafetyandmaneuverabilityofavehicleandtocontrolmultiplesmallsatellitesfortheobservationofmagneticfields.Thesafetyandmaneuverabilityofautomobilesareimprovedbyactivelycontrollingsteeringaswellastheaccelerators/brakes,andinthisway,wewillbemorecomfortabledriving.Inaddition,satellitesareusedforcommunicationsandbroadcastingandareveryimportantinourlives.Itispossibletoincreasethecommunicationcapacitybycontrollingthesatelliteswithhighaccuracy,andthen,ourliveswillbeeasier.YuichiIkedaAssistantProfessorDr.Eng.DegreesfromtheUniversityofElectro-Communications,Japanin2006.Hisresearchint-erestsincludecontrolofnonlinearmechanicalsy-stemsanditsapplicati--on.Development of a Method to Achieve Safe and High-performance System Operation (Top) experimental vehicle which converted RC car.
