    • Electrochemical and Mechanical Changes on Fatigue Corrosion Damaged Surfaces 

      Băicean, Svetlana; Palaghian, Liviu; Ciortan, Sorin; Thompson, Mioara (Universitatea ”Dunărea de Jos” din Galați, 2008)
      The paper presents some surfaces changes aspects in fatigue corrosion damage based on electrochemical, mechanical profilometry and microscopically analyze of cylindrical and plate steel specimens. The researches have ...

    • Fatigue Sensitivity Analysis of a Ship Structural Detail 

      Chirică, Ionel; Giuglea, Ștefan; Beznea, Elena-Felicia (Universitatea ”Dunărea de Jos” din Galați, 2009)
      In the paper, a FEM analysis used for fatigue assessment, based on the rules, was done. The approach for fatigue assessment in the early design stage of the ship structure has been developed. To overcome the challenges due ...

    • Modelling of Some Degradation Processes by Corrosion Fatigue of Metallic Surfaces 

      Băicean, Svetlana; Buciumeanu, Mihaela; Palaghian, Liviu (UDJG, 2011)
      Based on the well known fatigue corrosion effects, the mechanical stress and the corrosive environment have a significant effect on the prediction of the lifespan of the equipments that work in corrosive environment, two ...

    • Surface Roughness Parameters Evolution Under Fatigue Loading 

      Mereuță, Valentin V.; Palaghian, Liviu C. (UDJG, 2010)
      The main objective of this paper is to demonstrate that in order to have a complete characterisation of fatigue degradation it is necessary to analyze the evolution of surfaces roughness, which can become a stress ...

    • The Neuber’s Rule and a Correlation Between Fretting Fatigue and Plain Fatigue 

      Buciumeanu, Mihaela; Palaghian, Liviu (UDJG, 2010)
      Based on these experimental observations and on the remark that any small change on the discontinuity geometry has a significant effect on the stress distribution around it, a stress concentration factor is mandatory to ...
