Abstract : Hydroforming is a material-forming process that uses a pressurized fluid in place of hard tooling to plastically deform or to aid in deforming a given blank material (sheet or tube) into a desired shape. This process is gaining acceptance in various industries. The reasons for the interest in computer modeling of the tube hydroforming processes are mainly economical. Since the majority of tube hydroforming processes require high pressures it is not possible to do try-outs using soft tooling. The goal of this thesis is to model this highly nonlinear process (Tube Hydroforming) numerically and comparing results with those obtained from various international studies and researches. Material model was obtained from international published work and has been validated numerically; results were used in simulating T-Joint hydroforming process. Model created and meshed using Abaqus® finite element package, tube mesh bandwidth was optimized using Reverse Cuthill-McKee method from Ansys® Fluent® CFD code which decreased solution time by more than 37%. Several pressures and coefficients of friction were used in the simulation process. The study concluded that increasing forming pressure will result in a better cavity and corner filling. Also it concluded that increasing forming pressure in the presence of friction will reduce material flowability to the forming zone and might hinder the final product. Finally, pressure optimization using shooting method was practical to find the right forming pressure and forming conditions subsequently.
