Probabilistic Simulation of the Mechanical Response of a Pre-Stressed Railway Sleeper: Initiation and Propagation of Cracks during Static Test

Abstract:

The paper deals with the mechanical response of a pre-stressed railway sleeper during a standardized static loading test estimations of the variability of the sleepers response and especially the probabilities of the occurrence of cracks of specific widths at specific load levels (as a consequence of random concrete parameters) based on the results of (3D) numerical models are presented. The paper follows on from and extends previous results obtained by the authors research team in cooperation with specialists from the sleeper manufacturing company ZPSV a. s.
