A model which is based on the hypothesis of stress-induced structural relaxation and the concepts of fictive stress for viscoelastic deformation of glass materials around the glass transition temperature is proposed. It expresses both linear and non-linear viscoelastic behaviors. For constant strain-rate deformation, it performs the stress-overshoot phenomenon observed in the condition of non-Newtonian flow. The model calculation reproduces fairly well the experimental results of Pd40Ni10Cu30P20 glass alloy, in particular, the development of stress-overshoot with increasing strain-rate and lowering temperature. Moreover, this model performs oscillatory behavior (stress-overshoot and -undershoot) which has been observed in many polymer solutions and glass alloy recently observed in stress-strain curves.
