    • Fem Analysis of the Spur Gears Press-Rolling Proces 

      Marian, Ionuț; Sas-Boca, Monica; Rus, Luciana; Suciu, Ramona-Crina; Tintelecan, Marius; Noveanu, Dan; Nistor, Liviu (Universitatea "Dunărea de Jos" din Galați, 2013)
      This paper presents the FEM (finite element method) analysis of the pressingrolling process, a new method for obtaining spur gears. Using symmetries, the 3D geometrical model was created for tools and for the initial ...

    • Influence of reduction scheme on hardness cold rolled strip mark steel ST 12 

      Neacşu, Marian-Iulian; Drăgan, Viorel (Universitatea "Dunărea de Jos" din Galaţi, 2016)
      The paper presents the results of the research on the influence of the evolution hardness scheme rolled steel, for the cold-rolled strip steel St 12. St 12 is intended for the manufacture of cold rolled strip stamping ...

    • Modelarea comportării cilindrilor de laminor 

      Maimon, Aurel - Dan (Universitatea "Dunărea de Jos" Galaţi, 2007)

    • Thermomechanical Processing of Microalloyed Steels Used for Naval and Oil Industries 

      Doniga, Ana; Vasilescu, Elisabeta; Istrate, Miltiade; Măcuță, Silviu (Universitatea "Dunărea de Jos" din Galați, 2005)
      This paperwork shows the laboratory experiments made on X60 and X65 steels with several intercritical thermomechanical treatment application. Two variants were used: “down-up” thermomechanical treatment with heating and ...

    • Upon Friction on a Ball Bearing - Outer Raceway Contact - I. Uniform Loading of the Balls 

      Irimescu, Luminița; Diaconescu, Emanuel; Berthier, Yves (Universitatea ”Dunărea de Jos” din Galați, 2006)
      The paper advances an analytical model to evaluate the effect of micro-slip on the friction losses at the interface of a normally loaded rolling contact. The model validation was done by comparing the theoretical results ...
