EXPERIMENTAL RESEARCH AND NUMERICAL SIMULATION OF LASER SHOCK FORMING OF TA2 TITANIUM SHEET Z.Q. Yao1,Q.L. Deng1,J. Hu1,F. Wang1 (1.School of Mechanical Engineering, Shanghai Jiao Tong University,Shanghai 200030, China) Abstract:Laser shock forming (LSF) was a new technique realized by applying an impulsive pressure generated by laser-induced shock wave on the surface of metal sheet. LSF......

)(School of Materials Science and Engineering, Harbin Institute of Technology, Harbin 150001, China)Abstract:Viscous pressure forming (VPF) is a newly developed flexible sheet metal forming process, the viscous medium can be applied on both sides of sheet metal blank to improve the formability of sheet metals. The influence of back viscous pressure on sheet metal forming is one of the key problems......
. Flexible forming using plasma arc (FFUPA) is a newly developed technique, which produces deformation in metal sheet by thermal stress instead of external mechanical force. Without the requirement.... However, the investigations on FFUPA mainly focus on single-layer metal sheet (SLMS), and there is less public literature on the flexible forming of LCMS using plasma arc. Compared with the more......
that the higher the hardening rate of sheet metal is, the higher the forming limit is. A method for determining the reasonable flow stress-strain relation is recommended for describing the material behavior during inhomogenous phase and the forming limit of sheet metal. Key words: aluminum alloy; forming limit; sheet metal; flow stress-strain relation; inhomogenous deformation 1 Introduction Forming......
