Abstract

Short pulse laser micro-bending is intended as a non-thermal forming process utilizing the shock wave induced by laser irradiation to bend of micro scale components. In this paper, the bending behavior of a micro scale AISI 304 sheet was investigated during short pulse laser bending by the finite element method. A dynamic explicit analysis relied on incident wave for loading process was employed to obtain the effect of laser power and laser spot position on the stress and strain distribution and maximum bending displacement. Results show effect of laser power on bending process is more considerable in comparison with laser spot position.
