      On the influence of conformity on wheel–rail rolling contact mechanics 

      Blanco Lorenzo, Julio; Santamaría Manrique, Javier ORCID; García Vadillo, Ernesto ORCID; Correa García, Nekane ORCID (Elsevier, 2016-07)
      The aim of this work is to assess the effects of conformity on local contact related quantities at the wheel–rail interface such as traction distributions, subsurface stresses and frictional work distributions. For this ...

      On the study of train-track dynamic interactions caused by rail welds on discrete supported rails 

      Correa García, Nekane ORCID; García Vadillo, Ernesto ORCID; Santamaría Manrique, Javier ORCID; Gómez López, Josu (Elsevier, 2014-06-15)
      The paper studies the influence of rail weld dip on wheel-rail contact dynamics, with particular reference to freight trains where it is important to increase the operating speed and also the load transported. This has ...

      Wheel-rail wear index prediction considering multiple contact patches 

      Santamaría Manrique, Javier ORCID; García Vadillo, Ernesto ORCID; Oyarzabal de Celis, Olatz ORCID (Elsevier, 2009-06)
      This paper shows a new wheel-rail contact model specially suited to obtain wear indexes between wheel and rail when the vehicle negotiates tight curves. The model presented in the paper enables introduction of the two ...
