Determining material properties using impact wave propagation method

Thesis

Mechanically testing soft materials to identify dynamic material properties remains challenging in both theory and practice. Commonly used methods, the SHPB technique for example, have very limited capacity. One of the shortcomings is the impedance mismatch between bar and specimen: conventionally metal rods are employed, which generates a weak transmitted signal; also, the stress equilibrium assumption, on which traditional time domain analysis was built, is likely to be violated due to l...
