Research on Dynamic Behavior and a Failure-Model for GH4133B Superalloy

  • 摘要: 根据典型航空发动机机匣常用高温合金GH4133B在不同温度(298~1 073 K)、不同应变率(10-1~5×103s-1)下的力学性能试验结果,结合机匣包容性分析用的J-C(Johnson-Cook)本构模型在实际应用中本身存在的不足,提出了一种更为准确地描述GH4133B合金力学行为的修正J-C本构模型(modified J-C model,MJC model),同时结合GH4133B在不同温度、不同应力三轴度的破坏行为,建立了基于J-C时效判据的一个经验型的失效模型.通过模型预测结果与试验结果对比,发现所建立的本构模型和失效模型能很好地预测GH4133B塑性流动应力及破坏行为.
