A new specimen for investigation of the volume effect and scatter in fatigue data associated with different volumes is presented. This specimen contains two notches with associated volumes of different size. The WL-integral is used to estimate the probability of fatigue, and is compared to the experimental outcome. When the WL-integral is fitted to just one of the notches, the experimental outcome was well described. When fitted to both notches the fit was poor except at a failure probability of 50 %. The results are almost the same whether the WL-integral is evaluated as an area-integral at the specimen surface or as a volume-integral in the specimen volume. (C) 2010 Published by Elsevier Ltd.
