Název v původním jazyce

Stochastic analysis for short edge cracks under selected loads

Popis výsledku v původním jazyce

The article is focused on the exploration of fatigue damage to bridges and steel structures subjected to cyclic loading. Computational model is focused on fatigue crack propagating from the surface and it is based on linear elastic fracture mechanics utilizing the Paris-Erdogan&apos;s law. The behavior of the carrier element susceptible to fatigue damage is experimentally investigated on specimens with various types of load and it is expressed by a calibration function. For the prediction of fatigue damage over time, calibration functions for short edge cracks were derived based on the results of the experiment, and the acceptable size of the fatigue crack in damaged structural component under analysis was determined. Using the derived relationships, a stochastic analysis of the selected element was performed and the results are discussed.
