Abstract

We investigate plastic yield in glassy polymers subsequent to physical aging in the presence of a nonvanishing stress. Molecular dynamics simulations show that the applied stress does not alter the physical aging rate, but instead causes an apparent modification of the aging rate of the shear yield stress wi
