摘要
短裂纹的萌生与扩展是一复杂的非线性动力学过程,短裂纹扩展速率具有非线性动力学系统的混沌现象和自组织特征。文中利用神经网络对短裂纹扩展速率进行时序数据建模与预测,取得较好的效果。
The initiation and growth of short fatigue cracks is a nonlinear kinetic process, and the short fatigue cracks＇ propagation rate is characterized as chaos and self-organized. The time serial of short fatigue cracks＇ propagation rate is modeling and predicting by using neural network in this article, and the good result is achieved.
