Abstract EN
Modeling material flow behavior is an essential step to design and optimize the forming process.
In this context, four popular metamodel types Kriging, radial basis function, multivariate polynomial, and artificial neural network are investigated as potential methods for modeling the flow behavior of 6013 aluminum alloy.
Based on the experimental data from hot compression tests, the modeling performance of these four methods was tested and subsequently compared from different aspects.
It is found that all the methods are capable of constructing models for describing the hot deformation behavior.
The merits of Kriging method over other three methods are highlighted when the sample size for modeling is decreased.
Furthermore, the applicability of Kriging method is validated while decreasing the sample uniformity with respect to temperature or strain rate.
It is proved that Kriging method is competent in modeling the material flow behavior and is the most effective one among the four popular types of metamodeling method.
