The multiaxial fatigue behaviors of the GH4169 nickel based superalloy under (650°C) were investigated using MTS809 tension-torsion fatigue testing machine.
利用薄壁管试样,在MTS809疲劳试验机上对GH4169镍基高温合金进行了650oC下的高温多轴拉扭低周疲劳试验,通过对应力应变迟滞迴线分析发现,拉扭分量应力应变迟滞迴线形状与试件的加载波形和加载路径相关,塑性应变不断增大。
To predict life of multiaxial low cycle fatigue more conveniently,a multiaxial low cycle fatigue damage parameter is proposed based on the crack extension characteristics and changes of the maximum shear strain and the corresponding normal strain on the maximum shear stain plane and the maximum shear strain plane is considered as the critical plane.
为了更简便地预测多轴低周疲劳寿命,通过分析裂纹扩展特点和最大剪应变面上的最大剪应变和相应的法向应变变化特点,提出以最大剪应变平面作为损伤临界平面,将最大剪应变和相应的法向应变作为基本的多轴疲劳损伤参数,建立了基于临界面法的多轴低周疲劳损伤参量。
To numerically simulate the stress-strain response of the components under multiaxial cyclic load- ing,an elastoplastic finite element analysis was adopted to thin tubular specimens under multiaxial proportion- al and nonproportional tension/torsion loading at high temperature.
为数值模拟构件在多轴循环加载下的应力应变响应,利用ANSYS分析软件对承受高温2轴比例与非比例循环拉扭加载下的光滑薄壁管件进行了弹塑性有限元分析。
