On polymorphic uncertainty modeling in shell buckling

Buckling is typically the governing failure mode of thin-walled shells. In particular, geometric and material imperfections have a major influence on buckling behavior. Small variations large effects load-bearing However, design shells still characterized by deterministic way thinking, in which uncertainties not yet been sufficiently considered. Even probabilistic approaches, false assumptions are often generated due to small amount experimental data. The focus this paper an appropriate uncertainty quantification based available Therefore, concept polymorphic modeling presented axially loaded with different types imperfections. Finally, idea for novel fuzzy-valued safety level introduced. intended initiate rethinking methodology numerical quantification.
