Abstract

A novel laser high speed punching is presented. The laser induced shock wave acts as a punch. The forming speed can be controlled by adjustment of the laser energy. The previously-reported experimental results show that laser high speed punching is possible. This paper reports an investigation into the laser high speed punching process through finite element simulation. The Johnson-Cook model shear damage model is used as the fracture criterion for laser high speed punching. The finite element method was applied through the use of ANSYS/LS-DYNA code.
