title = "A study on effect of foam on the vibration quality of aluminium structure under combined loading",
abstract = "Foamed structures are being used in the body of vehicles and act as a shock-absorbing component under impact loading. Previous studies explored the impact and buckling resistances of foamed aluminum tubes. The purpose of this current study was to investigate the effect of introduction of foam on the damping characteristics of an aluminum tube under vibration. Two identical {"}L{"} shaped aluminum tubes were used for the experiment with one filled with structural foam. The {"}L{"} cantilever beams were chosen over the straight beam to simulate a more realistic combined loading condition of bending and torsion. The natural frequency of the system was determined analytically. The experimental results were compared and showed an acceptable level of error. The damping ratio of the aluminum tube with the foam showed an average increase of about forty percent in comparison to the tube without foam, indicating a significant increase of energy loss due to foam insertion inside the aluminum tube. Data were compared with similar experimental results from the literature and a good correlation was observed. This research project was carried out as a component of a graduate-level vibration course offered by the Mechanical and Electrical Engineering Department at Georgia Southern University.",
