To determine the reversal error , the loading cycle is to be absorbed up to the nominal force 为了确定反转误差,载重循环要能承受起标准力。
Output signal of the mechanically unloaded transducer with mounting parts at the start of a loading cycle 在装载循环起点有固定部件的机械空载力传感器的输出信号。
Still , the microstructure of the alloy during different loading cycles is researched with the help of tem , especially the evolution of the dislocation and dislocation bands during the fatigue process 此外,利用透射电镜的方法观察了在不同循环加载历晚条件下合金中微观结构的变化情况,尤其是位错以及位错带的演变规律。
According to our experimental investigations of varying load amplitude , it was found that the phenomena of fatigue crack growth retardation occurred for pmma material following a high overload cycle exerted among the regular constant amplitude load cycles , the ratio of peak value of overload to that of the regular cycles should be over at least 1 . 35 to make the retardation taking effect . the experiment scheme for measuring the shutting - off ratio of overload ( defined as the overload ratio when da / dn < 10 - 7 / cyc . ) 本文试验分析了变幅载荷对裂纹扩展的影响,证实了有机玻璃也存在超载迟滞现象,通过金相观察分析,提出超载迟滞的过程实际上是裂纹前缘萌生新的裂纹的过程的观点,同时提出超载迟滞的合理的解析,并且给出超载迟滞比,为随机载荷下疲劳扩展模型的建立提供了一个重要的参数。
Firstly , the experience of cfrm study is summarized and experiments are carried out to improve the preparation technics and to get the appropriate proportion of the materials used . secondly , the factors , which affect the conductivity and stability of cfrc , are investigated . and its smart property is studied with different cf contents and loading directions , and under elastic loading cycles 其次,通过试验,探讨了碳纤维含量、水灰比、骨料粒径、龄期、极化效应、电极形式等对碳纤维混凝土导电性、稳定性的影响;研究了碳纤维掺量、加载方向等对碳纤维混凝土机敏性的影响;并研究了在弹性范围、循环荷载作用下,材料的压敏性。
( 4 ) it was figured out that variational history of incremental dissipated hysteretic energy of high strength concrete tentative frame columns under different loading cycle levels ; through analyzing all sorts of damage models comparatively , damage model of high strength concrete frame column are put forward , which offers good basement for further damage analysis ( 4 )计算出高强混凝土试验框架柱的累积滞回耗能随加载循环水平的变化,通过对各损伤模型的比较分析,提出了高强混凝土框架柱的损伤模型,为进一步进行损伤分析打下了良好的基础。
