| Abstract: | This paper,by means of traditional thick walled cylinder theories and Tresca yield rule,establishes the math relationship model between permissible inner pressure of composed concave die with different layers and total ratio of outside diameter and inside diameter.Lagrange multiplier method is used to optimige design of composed concave die's parameter,we have studied ways of improving loading capacity of composed concave die and decreasing its sizes. |
