Modelling by Finite Element Analysis Method of Stress State Establishing for an Alloy Steel
(Universitatea "Dunărea de Jos" din Galați, 2008)The paper presents some results about the tension state in samples subject to pure bending fatigue process. Numerical simulation based on finite element method was used. The tension field induced by a vertical deformation ... -
Nanostructured Surface for 38MoCrA109 Steel by Nitriding in Nitrogen Atmosphere and Yag;Nd Pulse Laser Activation
(Universitatea "Dunărea de Jos" din Galați, 2008)YAG:Nd pulse laser is usually used for cutting and welding. The paper is based by experiments using YAG:Nd pulse laser (KVANT 17-CIS made). Technological modules were assembled for laser beam deviation and for relative ... -
Surface Hardening Over 38MoCrA109 Steel by Yag:Nd Pulse Laser
(Universitatea "Dunărea de Jos" din Galați, 2008)Laser offers unique capabilities for high energy concentrations at small surfaces. Factors that have influences over interactions between laser beam and steel surfaces have very high control. Pulse laser YAG:Nd is usually ...
