Pulsating hydroformingHydroforming is a sheet forming process proposed in the last decade. The numerical simulation of this process requires biaxial stress–strain curves which can be obtained by performing a pulsating hydraulic bulge testBulge test. In this study, the input parametersParameters of a pulsating hydraulic bulge testBulge test with titanium alloy sheets (Ti-6Al-4 V)Ti-6Al-4V are optimised using the Bees Algorithm (BA). The input parameters are amplitude and base pressure; bulge height (h) and minimum thickness (t) at dome apex are outputs. The mathematical modellingModeling of h and the design of an objective function (J) are needed for optimisation. A second-degree polynomial equation is derived for h using curve fittingCurve fitting for three frequencies. Additionally, t is calculated depending on h. The objective function is designed for maximum normalised bulge height and minimum normalised thickness. The results show less thinning at the dome apex with a bulge height similar to that of the traditional monotonous method. Thus, a uniform thickness distributionThickness distribution, which is a critical qualityQuality indicator in hydroformingHydroforming, is obtained with acceptable loss in bulge height. After optimisation, Δt (t-t0) is improved by approximately 9%. The bulge height increases by 15 and 13% in the best experimental case and the BA-optimised results, respectively. Consequently, the ductilityDuctilityof Ti-6Al-4Ti-6Al-4V V sheet is increased, and the input parameters are optimised.
