Before placing the tube in the die it is often preformed, by bending or crushing, into a shape that fits in the die cavity. R8.03.2 (64bit) . In this work [1], tube hydroforming was modeled using a Lagrangian finite element code with a history-dependent internal state variable material model. The hydroforming process was numerically optimized using the strategy shown in Figure 9. However, due to the varied cross-sections of the rim and the low formability of high-strength steel, it is difficult to produce thin-wall and defect-free wheel rims to realize the purpose of light weight. It is done by exerting a highly pressurized fluid force of up to 10,000 PSI onto a piece of metal to change its shape. Initially the tube is filled with a fluid, usually water. . Thus, the only design variables which were considered are related to internal uid pressure path. To validate Instructions to use calculator . This is quite important in mechanical applications.
