Micromechanical Plastic Behavior of AA5454 Alloy used for Fabrication of Pyramidal Cups

The present work was to estimate plastic behavior ofAA5454 alloy to fabricate pyramidal cups. The design procedure for the finite element analysis was carried out as per Taguchis techniques using ABAQUS software code. The step depth of incremental deep drawing was the critical process parameter influencing the plastic deformation of pyramidal cups. von Mises stresses induced in the cups are within the range of 240 300 MPa which is the limits of ultimate strength of AA5454.
