On Estimation of Residual Stresses in Rails Using Shake-Down Based Method
Journal Title: Archives of Transport - Year 2010, Vol 22, Issue 3
Abstract
This paper presents a method, which may be used to determine residual stress distribution in bodies subject to cyclic loads. A mixed global/local version of the Meshless Finite Difference Method (MFDM) is used to devise a discrete computational formulation of a shakedown based residual stress calculation mechanical model for elastic-plastic bodies subject to cyclic loadings. Several 1D and 2D verification/validation tests are presented, including thorough discussion of results and conclusions regarding the details of computational model. The method developed is applied to determine residual stress distribution in a railroad rail subject to simulated contact load.

Impact of change in the structure of distribution system on incurred cost
In multi-tier distribution, in addition to suppliers and consumers there are also intermediaries who participate in the transfer of products from manufacturers to end consumers. The choice of the distribution system depe...
Non-parametric machine learning methods for evaluating the effects of traffic accident duration on freeways
Traffic accidents usually cause congestion and increase travel-times. The cost of extra travel time and fuel consumption due to congestion is huge. Traffic operators and drivers expect an accurately forecasted accident d...
Classification and Prediction of Traffic Flow Based on Real Data Using Neural Networks
This paper presents a method of classification of time series of traffic flow, on the section of the main road leading into the city of Gliwice. Video detectors recorded traffic volume data was used, covering the period...
