Abstract
In this paper, the crushing behavior of cylindrical conic absorber with corrugated surface subjected to axial compressive loading is studied by using finite element method. The role of corrugation is to control the deformation pattern and to decrease the fluctuation in the load-displacement curve. The effect of taper is to increase the crushing span. The deformation mode for taper corrugated circular tubes can be classified into progressive crush mode, in which compressive force fluctuates with the wrinkles forming one after another, and simultaneous crush mode, in which compressive force increases uniformly. A mode classification chart is produced for various combinations of wavelength, wave-altitude and taper angle. The cone with corrugated surface is superior to the cylinder with corrugated surface for energy absorption rate.
