**2. Finite element analysis**

 In this research work, the finite element simulation has been carried out for the prediction of failure in stretch forming of aluminium alloys. The FE simulation was carried out in Dynaform 5.8, commercially available dedicated software meant for metal forming applications. It contained the preprocessing (auto generated meshing, tool arrangements, draw bead location) and post processing factors (animation, forming limit plot, deformation). The Dynaform uses LS DYNA (it is an explicit time integrating dynamic solver) in conjunction with the preprocessor and the LS-POST post processor.
