Sažetak
Within the framework of this research, a new methodology was proposed for estimation of cyclic Ramberg–Osgood parameters i.e. cyclic behaviour of steels based on their monotonic properties using artificial neural networks. A large number of experimental data for steels were collected from relevant literature and divided into unalloyed, low-alloy and high-alloy steels, since previous research confirmed that statistically significant differences exist among cyclic parameters of different groups of steels. Detailed statistical analysis was performed by means of forward selection and monotonic properties relevant for estimation of each cyclic parameter of each group of steels were determined. Based on results of performed statistical analyses, artificial neural networks were developed, separately for each parameter and each steel subgroup, using only monotonic properties that proved to be relevant for estimation of particular parameter. Neural networks have been evaluated on an independent set of data, in comparison with experimental values and values obtained by existing empirical estimation methods. The new approach proved to be more successful than empirical methods for estimation of most of the cyclic properties and behaviour of different steel subgroups.
