An artificial neural network (ANN)‐based model was developed to analyse high‐cycle fatigue crack growth rates (d a/d N ) as a function of stress intensity ranges (Δ K ) for dual phase (DP) steel. The training data consisted of d a/d N at Δ K ranges between 5 and 16 MPa √ for DP steel with martensite contents in the range 32 to 76%. The ANN back‐propagation model with Gaussian activation function exhibited excellent agreement with the experimental results. The fatigue crack growth rate predictions were made to demonstrate its practical significance in a given real‐life situation.
Because of the wide range of data points used during training of the model, it will provide a useful predictor for fatigue crack growth in DP steels. 2008 7th World Congress on Intelligent Control and Automation Chongqing, China 2008 7th World Congress on Intelligent Control and Automation IEEE, (2008). 978-1-4244-2113-8 Binbin Dan, Kuisheng Chen, Ling Xiong, Zhijun Rong and Jiangang Yi Research on multi-BP NN-based control model for molten iron desulfurization, (2008). 6133 61, 10.1109/WCICA.20 • T.

A back‐propagation neural network was applied to predicting the K IC values using tensile material data and investigating the effects of crack plane orientation and temperature. The 595 K IC data of structural steels were used for training and testing the neural network model. In the trained neural network model, yield stress has relatively the most effect on K IC value among tensile material properties and K IC value was more sensitive to K IC test temperature than to crack plane orientation valid in the range of material data covered in this study. The performance of the trained artificial neural network (ANN) was evaluated by comparing output of the ANN with results of a conventional least squares fit to an assumed shape. The conventional linear or nonlinear least squares fitting methods gave very poor fitting results but the results predicted by the trained neural network were considerably satisfactory. This study shows that the neural network can be a good tool to predict K IC values according to the variation of the temperature and the crack plane orientation using tensile test results.
