Creep curve prediction of single crystal nickel - based superalloy based on projection concept 单晶镍基高温合金蠕变曲线的预测
Results showed that the curves of fatigue / creep have three stages at the 75 % stress and the curves of fatigue / creep have two stages at the 55 % stress 结果表明,在交变载荷最大值为75 %的应力水平下,其疲劳蠕变断裂曲线为3段式曲线;在55 %的应力水平下, 15小时内其疲劳蠕变曲线为两段式曲线。
And in data processing module , the based work of data analyse and creep curves drawing , and the advanced work of creep limit and extrapolate results resolving can be achieved under many kinds of test condition 数据处理部分可对各种试验条件下的数据进行分析并绘制出各种蠕变曲线,进而得到蠕变极限及相应的外推结果。
It is the first time to use the conventional espi system ( neither phase shifting nor carrier is used ) to continuously analyze the super low frequency vibration with high quantitative in the world 在火箭固体燃料动态力学特性研究中,时间序列法成功的给出了固体燃料的蠕变曲线和蠕变速率曲线,并且给出了其热变形和蠕变不同时刻的全场位移分布。
Using the three ? arameter solid model and the burgers four - parameter model to fit the creep curve separately , it was found that the burgers model can describe the creep process more well , and then provide parameters for finite element analysis of asphalt concrete cores for embankment dams 用三元固体模型和burgers四元模型来拟合沥青混凝土的蠕变曲线,发现burgers模型能够更好的描述沥青混凝土的蠕变过程,为土石坝沥青混凝土心墙的有限元计算提供参数。
