Abstract

Of relevance in many industrial applications, Vibration-based methods have been proved to be an effective non-destructive alternative for characterizing welded structures. Recent numerical investigations modeled the bond as a lumped mass connecting the (welded) portions of the structural element by linear springs, and found good agreement with experiments, providing a quantitative estimation of the welding rigidity. Here, we investigate the sensitivity of the proposed model to uncertain parameters, whose determination is not possible in any practical case, confirming its robustness and reliability for assessing the integrity of welded structures.
