Abstract
The dynamic compressive properties of starch-based biodegradable plastics were measured using a split Hopkinson pressure bar (SHPB) method. The relationship between the stress and the particle velocity for starch-based biodegradable plastics is determined by the impedance match method by means of a SHPB over the particle velocity range of up to 13.0 m/s. In addition, dynamic stress-strain curves of starch-based biodegradable plastics were measured over a wide range of strain rates from 10-5 s-1 to 104 s-1, using a quasi-static compression testing machine and a SHPB method. Young's modulus and flow stress are dependent upon the strain rate. Empirical equations for 7% flow stress are derived for the strain rates from 10-5 s-1 to 100s-1 and from 103 s-1 to 104 s-1. It is also found that the attenuation of stress waves is quite large and is also dependent upon the strain rate
