Paper Title :

Abstract : Circular tubes are commonly used as energy absorbers in engineering structures. Many attempts have been made to improve their energy absorption characteristics. One method of modifying this type of energy absorbers is adding discontinuities to these components. In this work we experimentally investigated the effect of size and the number of roundtype through-hole discontinuities on energy absorption capacity of aluminum and steel circular tubes. Different number of through-holes with 4.3mm and 7.5mm diameter drilled in the tubes of 120mm length, 50 outer diameter (OD) and1.27mm wall thickness. Under quasi-static crushing test it was observed that introducing first pair of holes to the tubes will cause an increase in the amount of absorbed energy in comparison with the plain tube without hole. Although b y increasing the number of holes, tubes will absorb more energy but increase in the size of discontinuities will lead to a reduction in the amount of absorbed energy E. Also results showed that steel have more energy absorption capacity than aluminum because of its properties. Experimental test validated by numerical modeling with FEA software of MSC/Dytran.
