METHOD FOR COMPUTATION OF HIGH-RATE TENSILE STRENGTH OF PLASTICS FROM STATIC STRENGTH DATA,

Abstract

This report covers an investigation to detrmine if the high-rate tensile strength of plastics can be calculated from the results of static strength tests at low temperatures. Nineteen plastics were investigated. A simplified version of a mechanical-chemical equation of state in conjunction with master rupture curves drawn from lowtemperature test data was found to be all that was necessary to determine this property. The report concludes that: (1) High-rate tensile strength may be calculated from static strength data by means of a simplified verions of a mechanical-chemical equation of state. (2) Shorttime strength in the elapsed time period of 3 to 13 milliseconds was found to be equivalent to the ultimate or static tensile strength at -32 F. (Author)
