COMREL Sample "Fatigue": Results

A parameter study on the ‘Rate’ (upcrossing rate of the mean of the load process) yields

or as reliability (1 - failure probaility)

You may also display plots of a cost function and of the partial safety factors from a parameter study. Various other results like sensitivities and elasticities (‘normalised’ sensitivities) can be visualised as bar-charts or pie-charts. All results are also printed on a well structured ASCII-file. Additionally, the iteration history of the algorithm finding the most likely failure point (ß-point) and many other intermediate results can be dumped into a monitoring file. This file will also contain a detailed error report in case of problems.
