Abstract

The objective of this study is to formulate the statistical distribution functions for the viscoelastic creep compliance of a vinyl ester polymer. Short-term tensile creep/creep recovery experiments are conducted at two stress levels and at three temperatures below the glass transition temperature. Strain measurements in the longitudinal and transverse directions are measured simultaneously using the digital image correlation technique. The creep compliance functions are obtained using the generalized 3-D viscoelastic constitutive equation with a Prony series representation. Weibull and lognormal distributions are considered for the probability distribution of the creep functions. This effort involves an analytical study based on experimental results for representing the data scatter in polymer composites. Such a study has not been found in the literature.
