AI总结:

针对铝合⾦高周疲劳S-N曲线表征耗时成本高的问题,提出基于LSTM的迁移学习框架,用轴向疲劳数据训练模型迁移预测高周扭转S-N曲线,可降低测试成本并优化测试优先级。

摘要:

铝是一种应用广泛的合金,易发生疲劳失效。表征材料的疲劳性能极其耗时且成本高昂,高周数据的获取尤其如此。为缓解这一问题,研究人员开发了一种基于迁移学习的框架,该框架采用长短期记忆网络(LSTMs):先基于Al 7075-T6合金的纯轴向疲劳数据训练源LSTM模型,再将该模型迁移以预测高周扭转S-N曲线。该框架能够在高得多的循环范围内准确预测铝的扭转S-N曲线。研究认为,该框架将大幅降低获取不同材料疲劳特性的成本,并有助于在更优的成本和时间约束下确定测试优先级。

英文摘要:

Aluminum is a widely used alloy, which is susceptible to fatigue failure. Characterizing fatigue performance for materials is extremely time and cost demanding, especially for high cycle data. To help mitigate this, a transfer learning based framework has been developed using Long short-term memory networks (LSTMs) in which a source LSTM model is trained based on pure axial fatigue data for Aluminum 7075-T6 alloy which is then transferred to predict high cycle torsional S-N curves. The framework was able to accurately predict Al torsional S-N curves for a much higher cycle range. It is the belief that this framework will help to drastically mitigate the cost of gathering fatigue characteristics for different materials and help prioritize tests with better cost and time constraints.
