-
摘要: 复合材料结构声疲劳问题是许多工程技术人员关心的课题,经常采用数值方法对其进行分析.利用边界元法对其动力响应情况进行了数值模拟,并发展了一种可以进行复合材料结构声疲劳完整数值模拟的方法.所得结果可以为预测复合材料结构的声疲劳寿命提供参考.Abstract: Acoustic fatigue of composite structures concerns many researchers. Numerical simulation is often used to deals with this problem. In this paper, BEM is used to simulate the dynamic response of composite structures, and a numerical simulation method of acoustic fatigue of composite structures is presented. The results can provide references for forecasting acoustic fatigue life of composite structures.
