Behaviour of Tube under Axial Crush Load with Considering Effect of Heat Exchanged

Abstract:

Based on Johnson-Cook constitutive equation energy absorbed by tubes under axial crush load is studied by using Singace fold model with considering strengthening effects of strain rate,strengthening effects of strain and softening effect of temperature which should consider heat exchanged ; the total energy absorbed by tubes,mean load and load-displacement curve are obtained by method of divided step fold; and the relation between them and radius of tube,thickness of tube,fold velocity of tube is analysed.
