Abstract: The characteristics of optimization models for the united
creep damage constitutive equations is discussed. The reason of fail of
using the traditional gradient-based methods to optimize the problem is
analysed, and the characteristics for the optimization methods which are
adaptive to solve the kinds of problems are given. The evolutionary
algorithm is used to optimize this problem and the better result is
achieved. The conclusions may be helpful during optimizing the similar
problems to this.
Key words: Constitutive equations Creep damage Optimization
