Abstract

In this study, the numerical and experimental study of energy absorption and deformation of thin-walled tubes with square geometry and circular cross under impact loading is studied. The purpose of this study was to investigate the effect of geometry on the energy absorption of ALUMINUM tubes and the effect of foam filled tubes to absorb more energy under transverse impact.In the experimental part, hollow ALUMINUM tubes filled with solid POLYURETHANE FOAM were prepared and then the quasi-static tests with static and dynamic loading rates were performed by drop hammer method on samples with different energy and the acceleration-time diagrams in each test were obtained. In the last part of this study simulation of the phenomenon of transverse impact on thin sections was carried out with the ABAQUS software. The discussion and conclusions of this study and the results of experimental tests carried out by the author of the thesis have been compared with the results of numerical analysis and show a good agreement (difference below twenty percent). Finally, it was concluded that with regard to material of structure, at high energies square tubes have 50 percent specific energy absorbed higher than circular tubes and filled tubes have 20 percent specific energy absorbed higher than hollow ones. Also, transverse displacement of the hollow tube and circular tube is always higher than the filled tube and square tube.
