Abstract:

Measurements of the nonlinear viscoelastic behavior of two adhesives, FM-73 and FM-300, are presented and discussed. Analytical methods to quantify the measurements are given and fitted into a framework of an accelerated testing and analysis procedure. The single integral model used is shown to function well and is analogous to a time-temperature stress-superposition procedure TTSSP. Advantages and disadvantages of the method accessed with the latter residing primarily with the nature of the creep power law which is utilized.
