The Simplified Potential Energy Clock Model has been previously shown to predict accurately glassy polymer responses such as yield, creep, enthalpy relaxation, and physical aging It was now used to predict the behavior of monofilament Nylon fiber Even though the fibers showed process-induced anisotropy, the simpler isotropic model could be used to describe uniaxial tests The model predictions again accurately predicted a wide range of Nylon experimental data (C) 2010 Elsevier Ltd.
