In this paper, forming limit diagrams of DP780, DP980, TRIP590 and TRIP780 steel sheets were investigated for highspeed
sheet metal forming. The static and high speed forming limit tests were conducted with the aid of punch stretch
tests with arc-shaped and square-shaped specimens. The width of arc-shaped specimen was changed to compose the
uniaxial tension region of FLD and the friction condition was also varied to obtain the biaxial tension region of FLD. A
high speed crash testing machine with a specially designed high speed forming jig was used in order to realize the high
speed forming condition. The forming speed of each test condition was determined by comparing the results of the finite
element simulation and the experimental results.
