Abstract：Based on Johnson-Cook constitutive equation energy absorbed by tubes under axial crush load is studied by using revisted Singace fold model with considered strengthening effects of strain rate、strengthening effects of strain and softening effect of temperature; the total energy absorbed by tubes, increased temperture and load-deflection curve is obtained by method of step fold; the relation between energy absorbed and radius of tube 、thickness of tube 、fold vecocity of tube is analysed
