RESEARCH ON EXPERIMENTAL TEST FOR BUCKLING OF LIQUID-FILLED CYLINDRICAL SHELL UNDER AXIAL IMPACT

摘要

In this paper, experimental investigation for the dynamic buckling of liquid-filled cylindrical shell under axial impact is carried out thoroughly. The internal pressure and number of half-waves for axial buckling is measured. The curves of impact force and liquid pressure are drawn out. The developing process of buckling modes is demonstrated. The effect of materials and geometric parameters to buckling is discussed. Finally, the discussion of some important problems is made.
