An Experimental Investigation to Study Energy Absorption Capabilities of Foam Filled Tubes In Oblique Loading Using Taguchi Method

127  AbstractAn Experiment is conducted to determine the effect of various parameters on performance of tube in oblique loading and optimize its crushing in the given environment..The Experiment was designed using Taguchi technique and the parameters like material density , tube thickness ,foam density and angle of loading were selected which have more influence on energy absorption ,specific energy absorption and specific total efficiency based on the available literature. The energy absorption was measured from the load –displacement graph obtained from UTM . The results obtained from this experimental process were analyzed using ANOVA and the empirical formulae predicting the energy absorption, specific energy absorption and specific energy efficiency were determined for tube under oblique loading.L16 array was used ,which is a full factorial array and conducted experiments using tube material, tube wall thickness, filler material density and angle of loading as the 4 factors with 2 levels , low and high.
