...A. Goel; Y. Wen; J. Hein; M. Negahban; J. A. Turner The development of anisotropy as a result of isothermal plastic deformation below the glass transition temperature is investigated for different deformation temperatures. Initially, isotropic polycarbonate was subjected to different extents...

... the plastic strain rate and back stress at room temperature for polycarbonate. The evaluated results match well with results obtained by direct probing of the equilibrium stress, in which one searches for points at which the stress remains constant at a constant strain over long durations. The method proposed...
