Double indentation tests were performed to study the effect of process parameters on the mechanical performances of laser bended sheet metals. Sheets made of AISI 304, were laser bended by means of a High Power Diode Laser (HPDL), with different values of power and number of passes. The laser bending process was numerically simulated by means of the Finite Element Method (FEM). A thermo-mechanical model was implemented and calibrated by an experimental procedure. Un-processed and laser bended sheets were compared by performing double indentation in the Heat Affected Zone (HAZ). Finally, by comparing experimental and numerical results it was shown that FE thermo-mechanical model does not take into account the material annealing during forming; on the contrary, this effect is clearly visible in double indentation test results.
