The purpose of present research is to investigate the thickness distribution on the warm deep-drawing process of laminated sheets consisting of aluminum alloy series 1050, 5052 and stainless steel 304 (SUS), experimentally. Individually for each layer, the influences of blank temperature and grain size on thinning behavior are clearly demonstrated. In order to survey the thinning behavior in laminate sheet behavior during warm deep drawing process; three blank temperatures namely, 25̊ C, 100̊ C and 160̊ C are examined. Moreover, to obtain different grain sizes, the aluminum sheets are annealed at 350̊ C, 400̊ C and 450̊ C for 1 hour. Results indicate that increasing temperature and grain size lead to maximum thinning in all layers in Al 1050/SUS and Al 5052/SUS specimens increase. In addition, the most susceptible zone to fracture in aluminum sheets (Al 1050 and Al 5052) is punch profile radius region; nevertheless, for stainless steel sheets this zone switch to central zone of formed cup. These can be attributed to the fact that the adhesive layer play a crucial role in thickness distribution of steel 304 layer, therefore the distribution of thickness strain for adhesive layer is also nvestigated.
