The prediction of optimized forming parameters viz. the punch force, blank holding force, forming factor, and hydrostatic pressure will contribute to cost reduction of the processed metal through curtailment in material usage and manufacturing time. This article involves modeling of symmetric and axisymmetric sheet forming and hydroforming, rubber forming and axisymmetric incremental sheet forming; followed by numerical simulation using Explicit Finite Element Analysis program in ANSYS and ABAQUS. The present results are validated with previous experimental readings to check the feasibility of simulated analysis. The comparison reveals that both the readings show sound agreement in thickness distribution and load-displacement relationship. The enhanced formability in hydroformed products has been clarified by comparing with the forming factor and thickness variation. The result shows that forming factor increases with friction coefficient; thereby clarifying the need of sufficient friction to overcome cup failure. Moreover, the developed model highlighted wrinkling phenomenon in conventional forming.
