Abstract

Uncertainty quantification is crucial for the design of resource-efficient and reliable structures. Uncertainties of the material properties arise naturally in the production process and have significant effect on the structural behavior. In this work, a novel method for the uncertainty quantification of inelastic materials and structures is presented. The method is based on a separation of random but time-independent from deterministic but time-dependent behavior. As a result, only a low number of deterministic time-dependent basis functions are calculated. This allows uncertainty quantification at greatly reduced costs.
