On the influence of conformity on wheel–rail rolling contact mechanics
(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 non-proportionality between wheel/rail contact forces and speed during wheelset passage over specific welds
(Elsevier, 2018-01)
This study investigates the influence on the wheel-rail contact forces of the running speed and the shape and position of weld defects along the track. For this purpose, a vertical dynamic model in the space domain is used. ...
A contact mechanics study of 3D frictional conformal contact
(Elsevier, 2018-03)
A contact mechanics study of three-dimensional conformal contact with friction is presented, based on numerical calculations with Finite Element models and an extension of Kalker's exact contact theory which takes into ...
Dynamic comparison of different types of slab tracks and ballasted track using a flexible track model
(Sage Publications, 2011-11)
The dynamic performance of a ballasted track and three types of slab tracks is analysed and compared by means of a comprehensive dynamic model of the train-track system, generated using two commercial analysis software ...
Karakousis's Abdominoinguinal Approach for The Treatment of a Primary Retroperitoneal Parasitic Leiomyoma with Inguinal Extension. A Case Report
(Elsevier, 2018-01-09)
INTRODUCTION: Primary retroperitoneal parasitic leiomyoma (PRPL) with inguinal extension is a diagnostic-therapeutic challenge due to its uncertain etiopathogenesis and because it has been considered unresectable according ...
Comunicación Política en tiempos de Nueva Cultura Política
(Asociación científica Icono 14, 2020-01)
