Abstract

At present, commonly used methods to identify Burgers model parameters have subjectivity shortcomings. This paper adopts 1stOpt software with unique nonlinear fitting function. The stress-strain-time equation can be obtained according to constitutive equation of Burgers model. Then four parameters of the Burgers model can be obtained by fitting the experimental data directly. Compare with the parameters precision obtained by the subsection fitting method and Lsqcurvefit method and the results show that 1stOpt method has high recognition precision and accuracy.
