abstract:
In order to handle uncertainties, which unavoidably affect structural analysis,
traditionally the probability theory has been an essential cornerstone. Nevertheless, recently
criticism has arisen towards the effectiveness of building a Probability Density Function to
characterize the uncertain properties when experimental data are not sufficient to justify it. In
this context, the interval model has proved to be a useful tool to face the lack of knowledge
characterizing early stages of the design process. The aim of this paper is to compare
structural responses obtained by applying the interval and stochastic approaches to
incorporate uncertainties into finite element analysis.
