In this study, the influences of temperature variation in deep drawing process are investigated by changing the temperatures of the whole blank, a part of the blank, the punch and die for different yield criteria and hardening models. Von-Mises criterion with isotropic, kinematic and combined hardening and Hill48 and Yld2003 yield criteria are considered to form the constitutive relations. Circular, square and complex shaped parts made of AA5754 material are used in the numerical analyses. The local heating simulations are conducted for circular blanks and the drawability of the parts are evaluated by using the Johnson-Cook failure criteria. Hot forming and quenching and local heating analyses are also carried out for the complex shaped part. The results obtained for different constitutive equations by the finite element analyses are compared with each other and experimental results according to thickness strain distribution, punch force variation and rim shape of the deformed blanks.
