Laser forming is a complex dynamic forming process. Its basic feature is the forming by thermal stresses, induced by irradiation of a laser beam. A two-layer model for laser bending is proposed, which is capable to describe the process in spite of many restrictions which have to be made. It is shown that the coefficient of thermal expansion is one of the most significant parameters for the process. The model shows the right dependence on the sheet thickness and the right order of magnitude for the bend angle which can be obtained in one step of the laser bending process. Possible extentions of the model are discussed, using experimental results which had shown that the neutral line lies at a relative thickness z/s0 = 0.65. © 1993 CIRP.
