Craze Growth in Stress Relaxation Conditions: Effects of Physical Aging

Abstract
Growth of crazes during stress relaxation has been examined under physical aging conditions at four temperatures, from ambient to 60 degrees} C, for a styrene-acrylonitrile copolymer. It was found that the craze length varies linearly in the logarithm of loading time. A transition from a high logarithmic growth rate to a rate some 4 to 6 times slower was found to occur with respect to aging time. The transition seems to move to shorter aging times as temperature increases. The slow growth rate seemed nearly independent of temperature for all four temperatures investigated and the rapid growth rate was approximately the same for the temperatures where it was observable at the aging times accessible in these experiments.Conference Dates
