Probabilistic Simulation of the Mechanical Response of a Pre-Stre Railway Sleeper: Initiation and Propagation of Cracks During Static

摘要

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