Abstract：

Based on the experimental results of the uniaxial tension test of sheet metal,a calculation method and formula is proposed in this paper to determine the limit strain of tesion instability. Two factors have been taken into consideration. the specific energy and the geometrical factor-the intial fluctuation of cross sections.
