Abstract

This thesis deals with the uncertainties of fiber composite structures that occur during manufacturing. These are summarized and their influencing variables are calculated with two different sensitivity analyses. Experimental designs are created and simulated by finite element methods (virtual testing). On this basis, the effective characteristic values for stiffness and strength of fiber composite structures are determined with open source programs (virtual allowables).
