Abstract Scope |
Energy return in footwear is connected to damping behavior of midsole foams, which stems from the combination of cellular structure and polymeric material behavior. Traditional EVA foams have been replaced by BOOST™ foams, which have a multi-scale structure, consisting of porous beads at meso-scale and thousands of small closed cells within beads at micro-scale. In this study, in situ lab scale and synchrotron X-ray tomography have been employed to study the evolution of the foam structure during compression. The effect of functionally graded foam microstructure and the effect of strain rate on the damage evolution were studied and will be discussed. |
