The Study of Bending Forming Using Finite Element Discretization

In the bending forming process, it is well known that the relation of the forces and the strains. But it is inexplicit about the dynamic process. This paper analysed the bending forming dynamic process of the pure T2 copper. A finite element mesh is printed on the top end surface of the specimen by a hairline greasy pen. The dynamic process was carried out on a bending machine, and shot by a digital camera. The photos of forming process were processed in order to make the analysis explicitly. Through contrasted the processed photos of the different times, the shape changing could be observed clearly. And the pure T2 copper would be bended more easier in the later period process.
