    • Measuring the Residual Stress of the Injection Moulded Polymeric Parts 

      Niță, Alexandra; Leițoiu, Bogdan; Goanță, Viorel; Bârsănescu, Paul (Universitatea ”Dunărea de Jos” din Galați, 2009)
      The residual stresses are usually introduced during manufacturing, and are caused by processes such as molding. This paper presents how the authors determine the residual stresses for the flat plates from ABS, PP and PS ...

    • Residual Stresses Effect on Fatigue Life of Rolling Contacts 

      Crețu, Spiridon; Benchea, Marcelin (Universitatea ”Dunărea de Jos” din Galați, 2008)
      The fatigue life tests carried out on two groups of ball bearings point out the positive influence of the compressive residual stresses induced by a previous loading in the elastic-plastic domain. The values of residual ...

    • A Three-Dimensional Elastic-Plastic Analysis of Rolling Contacts 

      Benchea, Marcelin; Crețu, Spiridon (UDJG, 2010)
      An analysis model has been developed to model the nonlinear strain rate dependent deformation of rolling bearing steel stressed in the elastic-plastic domain. The model is designed in the frame of the incremental theory ...

    • X-Ray Diffraction Analysis at Ultrasonic Welding 

      Dumitrache, Constantin; Bărhălescu, Mihaela; Sabău, Adrian; Comandar, Corneliu (Universitatea "Dunărea de Jos" din Galați, 2009)
      In the article [2] the author present experimental investigations regarding of residual stress distribution in weld bead vicinity of submerged arc welded naval plates. In this way, residual stresses from vicinity of weld ...
