Zusammenfassung:This paper is dedicated to applying the Fourier amplitude sensitivity test (FAST) method to the problem of mixed extension and inflation of a circular cylindrical tube in the presence of residual stresses. The metafunctions and the Ishigami function are considered in the sensitivity analysis (SA). The effects of the input variables on the output variables are investigated, and the most important parameters of the system under the applied pressure and axial force such as the axial stretch and the azimuthal stretch are determined.
