✦ Synopsis

Two sets of fatigue data corresponding to two different materials, a low-alloy steel 42CrMo4 and an aluminum alloy AlMgSi1 are used to validate a fatigue model, applicable to any combination of stress levels and ranges, formerly proposed by the authors. The results seem to confirm the applicability of the model showing its capability to provide linear and non-linear trends for the S-N curves that fit well, respectively, to the real data of the 42CrMo4 steel alloy and the AlMgSi1 aluminum alloy, including the percentile curve shapes.

## Abstract This study was designed to provide an experimental validation for a statistical model predicting past or future exposures to magnetic fields (MF) from power lines. The model estimates exposure, combining the distribution of ambient MF in the absence of power lines with the distribution
