Abstract:

The effects of both material data uncertainties of the constituents and of volume fraction deviations from the design values caused by the manufacturing process on the forecasted stresses in a spherical container of functionally graded material (FGM) are investigated. Specifically, a steel/alumina hollow sphere subject to internal pressure and homogeneous heating is studied. It is shown that even moderate uncertainties and deviations may cause large expectation ranges of von Mises equivalent stresses, and this issue may yet predominate over the question for the most reasonable homogenization scheme(s).
