Artificial neural networks are forms of artificial intelligence that learn correlative patterns between input and output informatio n without a specific model. Then they use the learned relationships to make pred ictions. Five back-propagation artificial neural networks were constructed to re cognize certain relationships in hydrogen attack to predict the time to incubate fissuring of 0.5Mo and carbon steel. Given the two parameters, environmental te mperature and hydrogen pressure, these neural network models can offer a predict ion with certain accuracy. The feasibility of the model was verified by the data from papers. It is proved that the ANN technology is applicable to the evaluati on of the complicated system of hydrogen attack, and also gives a base to develo p the expert system and residual life evaluation system for hydrogen attack.
