    • An Analytical Procedure to Incorporate the Bauchinger Effect on Fretting Fatigue Models 

      Buciumeanu, Mihaela; Palaghian, Liviu; Sousa Miranda, António; Silva, Filipe Samuel (Universitatea ”Dunărea de Jos” din Galați, 2009)
      This paper proposes a modification on SWT model concerning the prediction on fretting fatigue life, in order to take into account the material deviation from the ideal elastic-plastic behaviour, the so-called “Bauschinger ...

    • Damage Evolution of AL7175 and CK45 Alloys under Fretting Fatigue 

      Buciumeanu, Mihaela; Miranda, Antonio Sousa; Silva, Filipe Samuel (Universitatea "Dunărea de Jos" din Galaţi, 2007)
      There are several different parameters that affect the fretting fatigue behaviour of materials. The present work is focused on the influence of the wear damage evolution. Results of fretting fatigue experimental tests ...

    • Damage Prediction in Fatigue Corrosion Processes 

      Băicean, Svetlana; Palaghian, Liviu; Buciumeanu, Mihaela; Mereuță, Valentin (Universitatea ”Dunărea de Jos” din Galați, 2009)
      The paper aims to establish an algorithm for determining the values and evolution of the stress concentration factor in corrosive environment, and establish its influence on the fatigue strength of steel required in a ...

    • 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 ...

    • A test for Rapid Tribological Characterization of Bearing Steels 

      Gheorghieș, Constantin; Buciumeanu, Mihaela; Scarpete, Dan; Gheorghieș, Livia; Bold, Dorian (Universitatea "Dunărea de Jos" din Galați, 2012)
      In this paper is a study the influence of the material and heat treatment on the changes of the fine structure parameters of the superficial layer of triboelements during the first cycles of rolling contact process. The ...

    • 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 ...

    • Wear Behaviour of the AL7175 Alloy under Different Bulk Stress States 

      Buciumeanu, Mihaela; Miranda, A.S; Silva, F.S (Universitatea ”Dunărea de Jos” din Galați, 2008)
      In what concerns the stresses involved in the process, most wear tests (namely those in the pin on disc and the pin on plate configurations) are usually solely concerned with the stress state in the contact originated by ...
