Abstract

The continuum scale shock wave theory has been extensively used to characterize the compaction wave propagation in polymeric foams. However, experimental full-field measurements are scarce to validate such shock wave models. In this study, dynamic experiments with the help of ultra-high speed imaging in conjunction with digital image correlation (DIC) to characterize the compaction wave propagation in polymeric foams. A direct impact is applied on a polymer foam sample using a Hopkinson bar apparatus. The experiment is conducted by shooting a projectile directly at the specimen at an impact velocity of 90 m/s. Typical characteristics of the compaction wave such as compaction wave velocity, compaction wave profile, full-field particle velocities are obtained from the DIC measurements. Furthermore, using a non-parametric method, inertia stress and hence the full-field axial stress is calculated across the compaction wave.
