    • Hysteresis and Mechanical Fatigue 

      Frunză, Gheorghe; Diaconescu, Emanuel (Universitatea ”Dunărea de Jos” din Galați, 2006)
      The material dumping, known also as inner friction or, simply hysteresis, is considered to be related to energy dissipation in the volume of a macro-continuous medium. This phenomenon takes place when a more or less ...

    • 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 ...

    • Experimental Studies Concerning Damage of Two Lubricant Greases in Severe Working Conditions 

      Diaconu, Nicolae (Universitatea ”Dunărea de Jos” din Galați, 2006)
      In this paper certain results regarding behavior of two greases used in lubrication of rolling and rolling-sliding tribosystems are presented. For this aim, a specialised stand has been used. The experimental tests were ...

    • Researches of Distribution of Loading on Coils of Running Pair of the Latch 

      Dzhanakhmedov, Akhad Kh. (Universitatea ”Dunărea de Jos” din Galați, 2006)
      This paper gives the calculation procedure of pressure distribution on coils of running pair of latch at various loading schemes. Recommendations are provided for the choice of loading schemes of running pair, which ensure ...
