摘要

In this paper, a scheme to predict stress-stiffening effect on structures life assessment is proposed. The adopted methodology combines modal analysis and polynomial chaos expansion-based meta-model to evaluate stress distribution. It manages pre-stresses sources caused by manufacturing processes and quality control uncertainties.
