| Abstract: | A FEM model is made for the process of initial bubble stretching formation, whichextends the application of FEM to the area of manufacturing technology of film formation.In the paper, studies are made on the variation of radius and thickness distribution during theprocess from semifinished tube product to bubble. Some conclusions are drawn accordingly. |
