Abstract

MOTA-HERNANDEZ, C. I.; ALVARADO-CORONA, R.; FELIX-HERNANDEZ, J. L.  and  MORALES-MATAMOROS, O.. Analysis and Application of ANN to Layers of Bored Steel. RevActaNova. [online]. 2017, vol.8, n.1, pp. 94-108. ISSN 1683-0789.

Three models of artificial neural networks were analysed and applied: Multilayer Perceptron (MLP), Radial Basis Function Network (BRFN) and the combination of both models (RBFN & MLP) for the value of fracture toughness for boriding steels AISI 1045, AISI 1018 and AISI M2. The steels were exposed to a boriding treatment paste, using the model of Palmqvist type cracks, applying the model to the experimental cracking assessment toughness Balankin proposed by Campos and through the modification of the model T. Laugier fracture. The input data for each grid model taking into account the type of steel boriding, the generated layer thickness, the distance of the indentation and the indentation load. The networks were trained with data obtained experimentally under Vickers microindentation testing on iron boride layers at different loads. The data of the fracture toughness of the iron boride layer are compared with experimental data, obtaining errors of 5% for both models of neural networks.

Keywords : ANN's; Boriding; Fracture toughness; Indentation.
