F. Daver et Bw. Cherry, MODELING THE ELASTIC-MODULUS OF HDPE IN TERMS OF STRESS-DEPENDENT THERMALLY ACTIVATED RATE-PROCESS, Journal of applied polymer science, 59(3), 1996, pp. 453-457
If a three-element mechanical model incorporating a stress-dependent t
hermally activated rate process is used to predict the instantaneous a
nd anelastic components of elastic modulus of high density polyethylen
e, it is suggested that the measured elastic modulus determines the an
elastic response rather than an instantaneous response and, furthermor
e, it is related to an interlamellar shear rather than a slip process
in the crystalline region. (C) 1996 John Wiley & Sons, Inc.
