Physically-based modelling for sheet metal cone parts forming under blast loading

“…Besides, since most of the sheet surface in the area between the punch tips and the blank holder is given free rein to form, wrinkles may occur on the flange or product wall [2,3]. Therefore, conical parts are normally made by spinning [4,5], explosive forming [6][7][8][9][10][11][12][13], hydroforming [14][15][16], electrohydraulic forming [17] or multi-stage deep drawing processes [14,[18][19][20]. In the meantime, the application of explosive forming rises from reducing manufacturing lead times and cost and increase material utilization and reduce waste [21].…”
