Effect of net lattice on finite element numerical simulation of thermal pushing of Ti bending pipe

Thermal pushing forming is an effective technology for manufacturing bending pipes. In order to save the cost of the products by optimum of process, a commercial software Superform of MSC was used to simulate thermal pushing of titanium bending pipes. The division of net lattice has a great effect on forming of the pipes. The requirement of a precise simulation as well as a reduction of the calculation duration was highly needed, thus different lattice divisions were used. It is found that for the pipe with a small dimension in diameter, only one set of unit is used to make a whole simulation, while on the contrary, the mixture of different of lattices could be needed to overcome the difficulty for the simulation.
