Design and implementation of new experimental multiaxial random fatigue tests on astm-a105 circular specimens

•Multiaxial random experimental fatigue tests realized with a new specimen geometry are presented.•The proposed specimens' modal approach was numerically and experimentally validated.•The experimental results data are compared with that came from the proposed BVM method.•Fractography analyses of the tested specimens were performed. 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 Wöhler 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.
