    • The External Cylindrical Surface Rolling by Method of Cold Deformation 

      Ivanovic, Petar; Djordjevic, Ljubodrag; Dašić, Predrag (Universitatea ”Dunărea de Jos” din Galați, 2006)
      This report, by the shown methodology, tries to contribute to the effective solution of tasks in the field of studying and designing the processes and states. It also points out a possible way of achieving high techno-economical ...

    • Tribological Behaviour of CO-CR-MO and Uhmwpe the Components of Intervertebral Disc Prosthesis 

      Iliuță-Crețan, Monica; Munteanu, Florin; Gafițanu, Mihai (Universitatea ”Dunărea de Jos” din Galați, 2006)
      The Intervertebral Disc Prostheses consist of a modular system and his function is based on low intervertebral friction. As a result of friction forces acting to the spine structures, the intervetebral disc prostheses can ...

    • Ultrasound Action on Strength Properties of Polycrystalline Metals 

      Moraru, Luminița (Universitatea ”Dunărea de Jos” din Galați, 2006)
      The mechanical properties of pure aluminum were investigated by tensile test on the sample with average grain size between 60 and 1000 µ m. The stress strain functions given by the models are fitted to the measured points. ...

    • 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 ...

    • Upon Radial Fretting of Dissimilar Materials 

      Ciornei, Florina; Irimescu, Luminița; Diaconescu, Emanuel (Universitatea ”Dunărea de Jos” din Galați, 2006)
      The paper presents a state of the art concerning radial fretting for dissimilar bodies and fretting damage. Four simple fretting models are defined in the literature: tangential, radial, rotational and torsional. Only the ...

    • Wear and Irreversible Entropy Generation in Dry Sliding 

      Abdel-Aal, Hisham A. (Universitatea "Dunărea de Jos" din Galaţi, 2006)
      This paper examines the relationship between wear and the generation of entropy within the mechanically affected zone, MAZ, of a sliding material. It is postulated that wear is related to irreversible entropy generation ...
