| Abstract: | The drawing process of thick wall semi spherical heads is analyzed through dividing the billet into four regions.According to the characteristics of the stress distribution of these regions,the thickness variation law is theoretically studied.The theoretical calculation is compared with FEM simulation,and a reasonable conclusion is drawn. |
