Finite Element FE and Artificial Accepted 2 February 2015 Neural Network ANN have been employed for the purpose. In other words a prediction of Available online finite element results has been done using ANN. Ultimately results of two methods have been 2 February 2015 compared for different cases. Wing fracture is a well-known problem of the planes which Keywords Residual stress depends on various parameters. The J-integral is a vital parameter in evaluations of structure J-Integral fracture phenomena. On the other hand residual stresses play an influential role in fracture Crack formation. In the current work effect of residual stresses and crack depth on J-Integral has Finite element been investigated in a standard NACA0012-34 airfoil. As will be seen residual stresses and ANN crack depth influence J-Integral values. It also will be shown that predictions of ANN method are in a good agreement with those obtained by finite element method. 2015 Growing Science Ltd. All rights reserved. 1.
