【Abstract】 Based on the artificial NN theory, a new data processing method for the multi-cracked prismatic shaft torision problem is presented. By using the NN toolbox in MATLAB software, the fast simulation for the experimental results of the shaft rigidity and thus the determination of stress intensity factor at the crack tip is achieved. The examples prove that the method introduced in this paper is effective and convenient.更多还原
