In this paper, a previously proposed  constitutive equation that describes the behavior of viscoelastic materials is used to predict the behavior of PMMA (polymethyl methacrylate) under creep loading at different stresses and temperatures for varying amounts of time. The three parameters in the constitutive equation, k,α, and γ are found by performing calculations on data from three tensile experiments and two creep experiments on a viscoelastic material. A GUI MATLAB application was written that used excel data from the experiments as input to predict the creep response for PMMA at any load, temperature, and timescale. The results of several predictions are compared against experimental data and good agreement was found.
