dc.description.abstractIn this research, 2D and 3D FEM models are composed for the clarification of the effect of initial thickness distribution on its distribution after drawing and the residual stresses. In the 2D FEM, the minimum bare element numberwas determined in terms on both residual stress precision and calculation time. Based on the results of 2D FEM, the element numberin3D FEM wasdetermined. Using the obtained 3D FEM, the effect of initial thickness distribution was clarified with the combination of thicknessreduction. It was revealed that light reduction in thickness in plug drawing sometimes lead to increase of thickness deviation, against intuitiveprediction based on tube drawing without plug.On the other hand, increase of thickness reduction resulted in decrease of thickness deviation. The mechanism of thickness change was also examined.
