【 摘 要 】

In this study, a laser-assisted bending process is proposed, in which the external force is applied by magnets. The process can be used for bending the magnetic and non-magnetic materials. The experiments indicated that a large bend angle with reduced edge effect can be obtained by this process. The process was simulated by finite element method and a reasonable agreement was obtained between the experimental and simulated bend angles. It was experimentally observed that the micro-hardness after bending was greater than the original micro-hardness for mild steel as well as stainless steel work plates. In all the cases, micro-hardness reduced from laser-irradiated surface to opposite surface. Performance of the process as well as its ability to get accurately simulated bring out its potential of adaptability in industries.
