3D numerical study on laser bending of sheet metal

Laser bending is a recently developed and highly flexible metal forming technique.In this paper,3D numerical study on laser bending under temperature gradient mechanism are carried out with ANSYS software.A finite element model of temperatu refield is built,the dynamic temperature field and temperature disribution under provided conditions are analyzed according to the numerical sumulation trsults,the relationships between the technique parameters and the peak temperature,temperature gradient are investigated.
