Abstract
An analytical solution for temperature and deformation fields produced by laser forming is derived. The effects of process parameters are investigated on samples of different materials and thicknesses. Experimental tests were carried out using a high-power diode laser on a poorly conductive material (AISI 304) and a highly conductive one (AA 6013) to evaluate the accuracy of the proposed model. A 2D FEM is developed to calibrate and validate the new model. The model predictions are in good agreement with experimental measurements even under low scanning speed due to the effect of conductive heat exchange of the irradiated zone with surrounding material. Based on the achieved results, a simple method for optimizing the process productivity is also discussed.
