Abstract
This work extends the authors previous results on interval based uncertainty treatment in engineering problems. Uncertainty in the context of Finite Element Methods is represented in a form of fuzzy numbers. The representation of membership in the fuzzy set is limited to an interval form. Load, geometric and material uncertainty accounted for. Exact results were obtained in the case of load uncertainty and very sharp solution is achieved for the case of geometric and material uncertainty. Number of examples is introduced to illustrate this new approach.
