“…It has been shown by Spoorenberg et al [16] that close agreement can be attained between finite element analyses and experimental results for the averaged residual stresses over the web thickness and the flange thickness. The finite element model was not developed to simulate the residual stress gradients over the web thickness and the flange thickness.…”

“…Earlier publications by Spoorenberg et al [15,16] demonstrate a significant difference between residual stresses in hot-rolled and roller bent wide flange sections. In this paper residual stresses obtained from finite element analyses by Spoorenberg et al [16] have been summarized and normalized with respect to the yield stress of the material before roller bending to develop and present a residual stress model. It was found that the bending ratio does not influence the magnitudes of the residual stresses, allowing for a residual stress model representing all examined bending radii for 10 ≤ R/h ≤ 40.…”

“…The results have been published earlier by Spoorenberg et al [15]. The experimental phase was followed by the development of a finite element model to estimate the residual stresses in roller bent sections, [16]. This finite element model was used to simulate the complete roller bending process.…”

“…When bent about the strong axis the top flange and bottom flange experience plastic elongation and shortening in longitudinal direction respectively. Since the roller bending process involves plastic bending, the initial residual stresses prior to roller bending are altered due to the curving process [15,16].…”

A new downscale test rig is developed for investigating the contact between the wheel and rail under impact-like loading conditions. This paper presents the development process of the setup, including review and synthesis of the potential experimental techniques, followed by scalability, mechanical and operational analysis of the new setup. The new test rig intends to remedy the lack of dynamic similarity between the actual railway and the existing laboratory testing capability, by taking into account the factors that contribute to high-frequency dynamics of the wheel-track system. The paper first reviews the functionalities of the existing test techniques in the literature. Based on this survey, the category of the scaled wheel on the rail track ring is chosen. Afterwards, three potential alternatives are identified under the chosen category and the optimum mechanism is achieved through finite element modelling and analysis of the structures. A downscale test rig, consisting of multiple wheel components running over a horizontal rail track ring, effectively fulfilled the requirements needed for analogical testing of the wheel-rail contact behaviour. The new test rig is a unique experimental setup due to the involvement of high-frequency dynamic vibrations in the wheel-track system and analogy of the incorporated elements and loading to those of the real-life system. This paper further presents the results of some real experiments carried out using the newly-built setup to support substantial ideas behind its development.
