Abstract
Research progress on the optimization in order to obtain the value of material constants for a set of creep damage constitutive equations was presented, including (1) a brief review of continuum creep damage modeling and the designs of objective functions; (2) case study reporting the influence of the initial start points on the final results; and (3) discussion and conclusion. As far as the authors know, there is no any published paper addressing specifically on the influence of starting values on the final results. In order to overcome the difficulty or inaccuracy it is suggested in this paper to (1) check the accuracy of a particular set of experimental data, (2) review the method to depict the relationship between the stress level and minimum strain rate, (3) to design a better objective functions so that the convergence is ensured to all the stress levels.
