Static and Dynamic Measurement of Polyurethane Foam Strength and Energy Absorption Capacity
The current paper is concerned with testing of polyurethane foam in both static and dynamic conditions. The
cylindrical samples were made of an EUROPLASTIC polyurethane foam grade of 0,077 g/cm3 density. Tests data were
mathematically processed in order to draw characteristic tension vs. volumetric strain curves. The tests results reveal the
ability of foam to suffer volumetric compression over 80%. The comparison of static and dynamic tests results also highlight
the presence of viscosity that manifests by increase of foam strength in dynamic crush. For dynamic tests the dissipated
energy was calculated.
