| Abstract: | In this paper, the micro-scale bending process and mechanism were studied numerically with ANSYS and a FEM code, which could be used to investigate thermal mechanical coupling and finite deformation impacting problem. The distributions and evolution of temperature, stresses and plastic strain were shown in the paper. At the same time, the effects of laser beam parameters and materials constants on the bending angle were discussed, and compared well with the experimental observations. |
