fatigue deformation meaning in Chinese

疲劳变形

Testing study on fatigue deformation law of rock under cyclic loading
周期荷载作用下岩石疲劳变形特性试验研究
Testing study on fatigue deformation law of red - sandstone under triaxial compression with cyclic loading
周期荷载作用下红砂岩三轴疲劳变形特性试验研究
Based on a large numbers of model / simulation test of the intermittent cracked rock - like samples , fatigue strength , fatigue deformation and crack appear in preexisting cracks tips , the growth of crack , the pattern of crack coalescence are studied / analysed systemically by means of cyclic load and static load , in the course of the model test , the difference between cyclic load and static load of crack appear in preexisting cracks tips , the growth of crack and the pattern of crack coalescence are observed and analysed
在试验过程中，观察并分析了循环加载方式下，预置裂隙端部裂纹萌生、扩展、岩桥贯通模式与静载方式下的差异；探讨了疲劳裂纹萌生、扩展的机理，分析了加载频率、荷载水平对裂隙试样疲劳强度、疲劳变形(总变形和不可逆变形)的影响规律。
