INTRODUCTION
Much of the data describing the mechanical behavior of thermoplastics available to designers today stem from practices standard for conventional materials which neglect viscoelasticity. While these single-point data can be used for initial material selection, they are inadequate for assessing the structural performance of a design since time-dependence may not be properly accounted. In the cases where necessary engineering data do exist, they most often do not span an appropriate range of stress, time, temperature, or strain rate (1, 2). Thus, the current data on engineering thermoplastics may be inadequate to fully support the innovative use of these ...
