It is possible to reach a higher depth by using a convex punch instead of a concave die. In this study, sheet Electromagnetic Forming on a punch and sheet Electromagnetic Forming into a die are investigated. The electromagnetic part of the study is investigated analytically and its mechanical part is studied numerically. In order to couple electromagnetic with mechanical parts, no-coupling method is used. The obtained results are verified by comparing the obtained results with previous experimental ones in literature. Rate-dependent and rate-independent hardenings are taken into consideration for the mechanical behavior for material of AAl1050. Using appropriate hardening model for material yields acceptable results. Moreover, a convex punch instead of a concave die is used to reach to a higher depth in sheet Electromagnetic Forming.</font></span></p> <p dir="ltr" style="text-align: justify;"></p> High speed forming, Electromagnetic forming, Convex punch, FEM, Strain rate. 1 9 http://ijmse.iust.ac.ir/browse.php?a_code=A-10-1060-1&slc_lang=en&sid=1 E.
