Prediction and data analysis of current pulses from impact-loaded piezoelectric polymers (PVDF) (Polyvinylidene Flouride)
Piezoelectric polymers are useful in measuring shock compression waves. The resulting piezoelectric current is stress-rate dependent, providing detailed diagnostic information about the stress wave profile. Technique is presented to analyse, predict, and design a high quality impact experiment using Bauer polyvinylidene fluoride (PVDF). A data analysis program ''PVDF-AUTO'' has been developed, and written specifically for data analysis of direct impact experiments. Independent data analysis done by F. Bauer (Inst. St.-Louis) and ''PVDF-AUTO'' shows excellent agreement between the different data analysis techniques. Typical responses and data from which prediction of piezoelectric output can be carried out are presented. Typical gauge designs are shown. 8 refs., 4 figs.
