Problems Encountered in Superplastic Forming of Al 5083 Parts B.Gershon, I.Eldror, I.Arbel, J.Milo Israel Aircraft Industries Ltd, Ben Gurion Intl.
Materials and Experimental Procedure The object of the study were 2mm thick Al-5083-H18 SPF sheets, commercially designated by SKY Aluminum as “ALNOVI-1”, with a chemical composition of Al-4.7%Mg-0.7%Mn-0.15%Cr, per ASTM B209M.
The resulting UTS is about 25% below the minimum for O (annealed) temper, while YS and EL correspond to those of “O”.
Demonstration parts were successfully SPF prepared from Al-5083SPF and passed acceptance testing.

Zhang Jianhai et al. [1], Zhang Boyan et al. [2], Bo Jingshan et al. [3] proposed to use the minimum of dynamic FOS time history as the evaluating indicator; Zhao Jianming et al. [4] proposed to use the dynamic equivalent value method to evaluate slope stability; Liu Hanlong et al. [5] proposed to use minimum average FOS as the evaluating indicator; Bo Jingshan [6] proposed to use the average of slope dynamic FOS which is also called average FOS as the evaluating indicator.
In addition, EL-Centro wave is adjusted the maximum acceleration to 0.38m/s2 as another seismic input for slope stability calculation as well in this paper.
The duration for EL-Centro wave (EC wave for short) is 53.74s and the time step is 0.02s.
