The paper deals with a parameter identification problem for creep and
fracture model. The system of ordinary differential equations of kinetic
creep theory is applied for describing this model. As for solving the
parameter identification problem, we proposed to use the technique of neural
network modeling, as well as the multilayer approach. The procedures of
neural network modeling and multilayer approximation constructing
application is demonstrated by the example of finding parameters for
uniaxial tension model for isotropic steel 45 specimens at creep conditions.
The solution corresponding to the obtained parameters agrees well with
theoretical strain-damage characteristics, experimental data, and results
of other authors.
