  • Laser bending process was numerically simulated by the FEM software of MSC.Marc. The experiment results were compared with the simulation ones, and the temperature and displacement curves of experiment and calculation were in good accordance. The comparison indicates that, calculated model is regarded as correct and the calculated process is considered to be credible, and calculated result will lay foundation for chosen laser parameters. More irradiation paths influence on displacement effect was discussed by numerical simulation. Conclusions show that the order and direction of irradiation paths have a huge influence on displacement effect of specimen. The best type is regarded as alternate irradiation path with contrary directions from fixation to the end of free so as to gain uniform displacement along the width direction. At the same time, it provides theoretical basis for the chosen of irradiation paths of laser bending stiffened sheet metal.
