    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 ...
  • Ghimiși, Ștefan Sorinel (Universitatea ”Dunărea de Jos” din Galați, 2006)
    Fretting is now fully identified as a small amplitude oscillatory motion which induces a harmonic tangential force between two surfaces in contact. It is related to three main processes, i.e. fretting-wear, fretting-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 ...
  • 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 ...
  • 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 ...
  • Dašić, Predrag (Universitatea ”Dunărea de Jos” din Galați, 2006)
    In this paper it is analised the dependence regression between flank wear tools or wear out of belt width on the back surface VB and cutting time t in the form of complex power-exponential regression equation for turning ...
  • 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 ...
  • Capitanu, Lucian; Iarovici, Aron; Onișoru, Justin (Universitatea ”Dunărea de Jos” din Galați, 2006)
    Some studies report the failure of a tibial insert of knee prostheses due to the subsurface cracking and delamination wear [1]. The present study starts by analysing retrieved total knee prosthesis revealing the loss of a ...
  • Goanță, Adrian Mihai (Universitatea "Dunărea de Jos" din Galați, 2009)
    Through this paper the author demonstrates the indisputable advantages of parameter assigned design which through its own features provides the possibility of automatically obtaining technical drawings including the ...
  • Goanță, Adrian Mihai (Universitatea "Dunărea de Jos" din Galați, 2009)
    The paper intends to highlight, in the context of general geometrical modelling, the specific aspects of design and modelling of a gear pump. In practice in such situations containing toothed gear it is recommended to ...
  • Ghelase, Daniela; Dașchievici, Luiza (Universitatea "Dunărea de Jos" din Galați, 2009)
    According to this new approach, a machining system interacts with the “market” carrying out a certain “service” (machining “service”) for a specified “client” (the work piece), it establishes a full economic relationship ...
  • Haraga, Georgeta; Ghelase, Daniela (Universitatea "Dunărea de Jos" din Galați, 2009)
    AutoCAD is one of the most popular graphics programs that was created for the production of technical drawings in the 2d and 3d with a high precision. In this paper we have presented the basic primitives which can be ...
  • Gorlach, Igor A.; Ghelase, Daniela (Universitatea "Dunărea de Jos" din Galați, 2009)
    Many components and structures require protection against corrosion, oxidization, excessive heat and wear. This is achieved by applying various types of coatings on the component base material, hence providing the necessary ...
  • Efstathiou, K.; Varitis, Em.; Mansour, G. (Universitatea 'Dunărea de Jos" din Galați, 2009)
    In recent years, reverse engineering technique is used in the field of archaeology to model the geometry of archaeological findings. Modelling of ancient objects is a demanding process due to fragility. In this paper ...
  • Debeleac, Carmen (Universitatea "Dunărea de Jos" din Galați, 2009)
