Abstract: 

Escape of particulate material through a threaded connection during an impact event is important for understanding the performance of transport packaging. A methodology is presented for a relatively economical comparative measure of thread engagement utilising steady state heat transfer methodology to calculate a resistance to flow. Although this method does not provide a direct method of calculating the performance of the thread it allows comparison of different impact scenarios to provide information for designing test methodology.
