Finite Element Method Analysis of Stress Intensity Factor in Different Edge Crack Positions, and Predicting their Correlation using Neural Network method

Abstract

According to the fracture mechanics, crack propagation in the body of structures may lead to a failure. In this field, Stress Intensity Factor is utilized to determine the stress intensity near the tip of a crack, and to predict if a crack starts to grow. The crack propagation can be determined by comparing Stress Intensity Factor to the Critical Stress Intensity Factor. This study attempts to analyze the Stress Intensity Factor in various edge cracks along the length of a finite plate which is under a uniform tension. Finite Element Method is utilized for the analysis. In addition, Neural Network Method is used to predict the correlation of Stress Intensity Factor and the position of edge crack along the length of a finite plate.
