Abstract This study presents a novel approach for constructing master curves of rheological material. The approach conducts a calculation formula of the shift factor, which takes the area of the overlapping region between the shift curve and the reference curve as the determinant factor. The formula is succinct and clear. All the parameters come from the experimental data, that is to say, we can calculate the shift factor without interpolation or fitting. Thus, it makes the uniqueness and accuracy and escaping from the uncertainty of manual shifting subjective judgment and the error analysis of fitting of numerical shifting method. Meanwhile, because of the mathematical computing process of derivation, the formula is appropriate for all the materials satisfying the rheological simplicity. In addition, the applicability of the approach can be further strengthened by taking the significant peak value of the test curve into consideration. The effectiveness of the proposed approach is verified by an example of constructing dynamic mechanic property master curves of carbon-black rubber.
