Abstract
Multiaxial random experimental fatigue tests realized with a new specimen geometry are presented. Setting the circular specimen, it was possible to test ASTM A-105 material with a frequency resonance system. The proposed specimens’ modal approach was numerically and experimentally validated. The goal of this work was to demonstrate to be able to define the W¨ohler curve of the component made, using forecasts data came from the proposed BVM method. To complete the investigation, fractography analyses of the tested specimens were performed.File in questo prodotto:
