Abstract Titanium alloy sheets exhibit significant plastic anisotropy that can be attributed principally to the presence of texture. Such plastic anisotropy has pronounced effects on subsequent sheet metal forming and springback processes. In the present paper, cylindrical cup drawing processes with titanium alloy sheets TC1M of 0.8mm thickness were simulated using ADINA FEM software. Three sorts of shape distortions phenomena exhibit in the drawing cups fabricated in room temperature after elastic recovery process: the inner wall is no longer a cylindrical surface, the lip periphery becomes wavy and the thickness distribution becomes unhomogeneous. A series of cup drawing tests were conducted and reasonable agreement was obtained between the predicted and measured profiles.
