人工神经网络在实验断裂力学中的应用

Application of Artificial Neural Netwok Method to Experimental Fracture Mechanics

提出一种基于人工神经网络的多裂纹柱体扭转问题的数据处理新方法.运用MATLAB中的神经网络工具箱,对柱体的抗扭刚度实验值进行快速拟合,从而得到了裂纹尖端的应力强度因子.实例应用证明该方法是简便、有效的.

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.
