Axial Crush of Metallic and Hybrid Energy Absorbing Thin-walled Tubes with Polygonal Cross-sections: Numerical Analysis
Material properties and geometry are two important design parameters which their effects should be considered in a crashworthiness analysis. In this paper, the axial impact of metallic and hybrid energy absorbing thin-walled tubes with poly-gonal cross-section is simulated using LS-DYNA software. The combined effects of changing the geometry and material properties on the mass specific energ...
متن کاملStudy of Energy Dissipation in Accordion Thin-Walled Tubes under Axial Cyclic Loads
Energy absorber systems like metallic dampers for controlling the structural vibrations due to earthquake have witnessed considerable development in the past few decades. Also there are some studies on the energy absorption of thin-walled tubes due to impact load. Thin-walled tubes have a large deformation capacity and are suitable energy absorbers in the structure during an earthquake provided...

متن کاملEffect of Corner Bluntness on Energy Absorbing Capability of Non-circular Metallic Tubes Subjected to Axial Impact
The energy absorbing capability is one of the most important aspects of crushing behavior of a structure subjected to axial impact. In this paper, a simple practical method is introduced to enhance the crushing behavior of this kind of structure. The axial impact of metallic energy absorbing thin-walled tubes with special shaped cross-section is simulated using LS-DYNA software. The effect of c...
متن کاملInvestigation of the effect of buckling initiator on energy absorption of thin-walled circular tubes by using of numerical simulation
Cylindrical thin-walled tubes due to construction and easy installation, high energy absorption capacity are used in the automotive industry as an impact energy absorber. However, the main weakness of cylindrical tubes is in the high initial peak load. Therefore, in this paper, to overcome this weakness, a buckling initiator is used at the top of the tube. This buckling initiator is a steel rod...
