Fatigue and fracture behavior of pearlitic Grade 900A steel used in railway applications
(2016)In overloaded railway networks, rail surface defects developed under rolling contact fatigue (RCF) if left untreated, may propagate to the bulk of the rail and become critical for its structural integrity. To avoid critical ... -
A hybrid two-step approach for evaluating the impact of local rail defect on building vibration
(2017)With the development of light rail transit in urban areas, the effect of railway vibrations on buildings and people inside buildings is a growing problem. In particular, urban transit commonly generates large vibration ... -
Investigation of various nozzles configurations with respect to IFMIF and liquid walls concepts
(2015)The study of liquid-metal free surface flows is of great interest in the fusion research, for example in the IFMIF and liquid walls concepts. In the IFMIF project, the main goal is to test candidate metallic materials in ... -
Modelling the singular rail and wheel surface defect for predicting railway ground vibration
(2015)When undertaking a railway vibration assessment, the presence of singular defects on the rail and wheel surfaces significantly affects the ground vibration level. The objective of this paper is to analyse the most common ... -
Railway-induced ground vibrations in the presence of local track irregularities and wheel flats
(2015)Rapid growth in railway infrastructure has led to numerous environmental technical challenges. This includes ground-borne vibration, which is becoming an increasing problem, particularly in urban environments. A common ... -
Rolling contact fatigue of rails
(2013)Rolling contact fatigue (RCF) has been of increasing concern in the recent years regarding the safe operation of high-speed railway track with high traffic intensity. The present paper summarizes the results of an on-going ... -
Surface roughness analysis in high speed-dry turning of a tool steel
(2010)High-speed machining is widely applied for the processing of lightweight materials and also structural and tool steels. These materials are intensively used in the aerospace and the automotive industries. The advantages ...
