“…In order to enhance the degree of deformation, the laser bending process under the auxiliary load is simulated [6][7] for D36 for ship plate and stainless steel, their deformations are predicted. Research on laser prestressed bending of the complex structure of aluminum alloy plate is done and influence factors and material properties change during the bending process are analyzed [8][9].…”

The new method of laser prestressed bending of Titanium alloy sheet is put forward in this paper. Titanium alloy sheet is produced pre-deformation by a clamp, the laser beam with some certain intensity scans its surface along the given path, and it is formed due to the thermal effect of the laser to reduce the yield strength of the scanning area and enhance its plastic deformation ability. A feasibility experiment for Ti-6Al-4V sheet is done and the bending effect is remarkable. Laser prestressed bending mechanism is described and the main influence factors are analyzed.
