    • Experimental Investigation of Fatigue of Thin-Walled Welded Structures of Commercial Vehicle Frames 

      Fokilidis, Athanassios; Savaidis, Georgios (Universitatea "Dunărea de Jos" din Galați, 2007)
      The fatigue behavior of bus frame components consisting of thin-walled tube beams joined together by fillet welding has been investigated. Numerical analysis by means of finite elements and experimental stress analysis ...

    • Mechanical Resistance as a Function of Local Properties 

      Chiriță, George; Ștefănescu, Ioan; Soares, Delfim; Silva, Filipe (Universitatea "Dunărea de Jos" din Galați, 2007)
      The present study makes an estimation of an automotive engine piston mechanical properties and fatigue life based on some characteristics of metallurgical microstructure. Because it is intended to assess the properties ...

      Motoiu, Petra; Dumitrescu, Daniela; Fratila, Cornel; Trusca, Dacia (Universitatea "Dunărea de Jos" din Galați, 2007)
      The continuous increase of the applications of thermal sprayed coatings together with the demand for layers having always more and more enhanced performances and properties stimulates the research activity toward ...

    • Structural and Tribological Aspects on Ti(C,O,N) Magnetron Reactive Sputtered Thin-Films 

      Munteanu, Daniel; Olteanu, Camelia; Ionescu, Cristian; Munteanu, Alexandru; Vaz, Filipe; Cunha, Luis (Universitatea "Dunărea de Jos" din Galați, 2007)
      Magnetron sputtering is a flexible technique and allows producing a significant amount of types of coatings. Within the frame of present work, Ti-C-O-N thin films were deposited onto high-speed steel (AISI M2), substrates ...

    • Electric and Electromagnetic Properties of Fiber Fabric Based Filled Epoxy Composites 

      Cîrciumaru, Adrian; Andrei, Gabriel; Bîrsan, Iulian; Dima, Dumitru (Universitatea "Dunărea de Jos" din Galați, 2007)
      Electric and magnetic properties of laminate fiber fabric based epoxy composites are investigated through experimental techniques. Various concentrations of powder fillers were used in order to change the basic properties ...

    • Studies About Electrochemical Plating with Zinc-Nickel Alloys 

      Gutt, Gheorghe; Vasilache, Violeta; Poroch-Serițan, Maria; Vasilache, Traian (Universitatea "Dunărea de Jos" din Galați, 2007)
      The electrochemical deposition of zinc and combinations with elements of the 8th group of the Periodic System (nickel, cobalt, iron) have good properties for anticorrosive protection, compare with pure zinc. For steel ...

    • Intermetalic Copper Phase Characteristics and Links with the Gold Sphere in Alumina Cover Sheets 

      Benta, Marius Dan; Mogan, Petre Nicolae; Drăgușin, Georgiana (Universitatea "Dunărea de Jos" din Galați, 2007)
      The time period in which the intermetalic sheet cover is developed into the gold sphere in alumina is fully known being relatively not much literature regarding the morphology ant intermetalic phases growth in the copper ...

    • Severe Plastic Deformation an Advanced Method for Nanostructuring Shape Memory Alloys 

      Gurău, Gheorghe; Gurău, Carmela; Tănase, Dinel; Drugescu, Elena (Universitatea "Dunărea de Jos" din Galați, 2007)
      Severe plastic deformation (SPD) is an advanced plastic deformation. In this process nanostructuring metals and alloys may be produced. Nanostructured shape memory alloys are associate with a very high strength, toughness, ...
