Numerical simulation and experimentation of micro scale laser bulge forming

Simulation on deforming progress and stress evolution during laser shock forming with finite element method

“…4(c) and (d) respectively. This phenomenon also appears in earlier study on Cu sheet deformed by Zheng et al (2010) with laser shock. Fig.…”

Rubber-induced uniform laser shock wave pressure for thin metal sheets microforming

“…This technique originates from laser shock processing [3]. The applications of laser-shock-induced deformation on thin metal sheets have been drawing increasing attention [4][5][6][7][8][9][10]. Laser shock microforming can be achieved with or without a micro-mold [5,11].…”

Mold-free fs laser shock micro forming and its plastic deformation mechanism

“…Laser shock forming-a non-thermal laser forming method that has the advantages of non-contact, tool-free, high efficiency, and high precision-has been successfully introduced into micro manufacturing and has been reported as having great importance [5][6][7][8][9][10]. Generally, there are two categories of laser shock forming: with mold [5][6][7][8] and without mold [4,[9][10].…”

“…Generally, there are two categories of laser shock forming: with mold [5][6][7][8] and without mold [4,[9][10]. For the former, the maximal horizontal size of the formed microstructure is determined by the mold, and the laser parameters are the main influence on the vertical size.…”
