UNCERTAINTIES IN PROBABILISTIC NUMERICAL-ANALYSIS OF STRUCTURES AND SOLIDS - STOCHASTIC FINITE-ELEMENTS

The main sources of uncertainties involved in the analysis of structur es and solids are shown and the tools available to deal with them. Whi le trying to cover the complete modeling process, ranging from the pro blem formulation via the mathematical model all the way to the numeric al approximation, we have tried to expose areas in need of further res earch. The techniques and methods involved in stochastic modeling are explained in somewhat more detail, as they are newer and less known th an those used for the deterministic modeling.
