The choice of the process parameters in the conventional tube bending forming is often based on experience and adjusted by repeated bending tests. The method of constantly testing to adjust has seriously affected the production efficiency and increased production costs. In this paper, neural network is used to establish the intelligent prediction model of the pipe forming process parameters. Th...

Usually, fatigue tests on fibre-reinforced composites are performed in uni-axial tension/tension or tension/compression fatigue [1], providing the S-N data. Although bending fatigue tests are not widely accepted as a standard, they are used a lot for research purposes [2] and they do have some important advantages [3]. In case of three-point bending fatigue, the history of bending force versus ...
