A rotating ring in contact with a stationary load as a model for a flexible train wheel

Lu, T. (author), Metrikine, A. (author)

A load moving on a center-fixed ring and the reciprocal problem, namely a rotating ring subjected to a moving load have been used in several works to study the tire dynamics. In contrast, very few papers exist in which the ring model has been used in order to study the dynamics of a train wheel. In this paper, a thin ring model is introduced to...

Modeling and analyzing autogenous shrinkage of hardening cement paste

Lu, T. (author), Koenders, E.A.B. (author)

In this paper, a conceptual model for analyzing the plastic part of autogenous deformation of cement paste based on the Arrhenius rate theory will be presented. The autogenous deformation will be calculated from the elastic deformations with inclusion of creep. Different kinds of cement paste with a water cement ratio 0.3 are tested and studied,...

The development of area wide traffic management scenarios

Van Zuylen, H.J. (author), Lu, S. (author), Li, J. (author), Yusen, C. (author)

Traffic management in cities with congestion is a big challenge with still unused opportunities. Intersection control is a corner stone but this should be done in an area-wide context. The dominant traffic process on urban roads is the traffic flow on the intersections. Spill back is a most important cause of malfunctioning networks. The...

A mesoscale modelling perspective of cracking process and fracture energy under high strain rate in tension

Weerheijm, J. (author), Lu, Y. (author), Xu, J. (author)

This paper presents a numerical modelling study on the simulation of the cracking process and fracture energy in concrete under high strain rate. To capture the stress wave effect and the damage evolution at the meso-length scale, both a homogeneous model with a millimetreresolution mesh and an explicit heterogeneous mesoscale model with random...

Cake layers and long filtration times protect ceramic micro-filtration membranes for fouling

Lu, J. (author)

The objective of this research was to decrease membrane fouling of a ceramic microfiltration system and at the same time increase the recovery. A conventional operation in micro- and ultrafiltration is an in-line coagulation and a frequent hydraulic backwash. The idea about these frequent backwashes is to limit the accumulation of fouling on the...

The Evaluation of Traffic Control in Changsha City

Lu, S. (author), Li, J. (author), Van Zuylen, H. (author)

Different aspects of the traffic control system in the CBD of Changsha have been evaluated. A general issue is the safety conditions, which are evaluated qualitatively. The second issue is the low saturation flow observed on the intersections, that appear to be 20 to 30% lower than the ones in comparable situations in Europe or North America....
