This paper presents a case study for the strength demonstration of a railway wagon welded node using the probability approach. The design variables were taken from the existing standardization for railway vehicles. The fatigue damage summation method for proving the satisfactory service life as well as the Goodman diagram method for verification of the unlimited service life was used for the node examination. The probability estimation was made using the Monte Carlo SBRA method with the help of the Anthill software. and Obsahuje seznam literatury
We describe simulation approaches suitable for the full probabilistic reliability assessment of a concrete beam by the finite element method. We compare the direct Monte Carlo method with a variance reduction technique based on Importance Sampling. A material model for the concrete beam is presented. The obtained results of the reliability assessment are discussed. and Obsahuje seznam literatury
