Theobserved strain is 10~2 times as local point strain at the same observed stress.This indicates that macroscopical symmetrical rock is quasi-brittle materialwith microcosmic heterogeneousness and its macroscopical mechanicalbehavior is the results of reciprocity and magnification between microcosmiccharacteristic, not simple sum.(4) The degree of irregularity of strain increases with the number of cycle.But degree of irregularity of transverse strain fluctuates larger at the samecycle. Moreover degree of irregularity of transverse strain is larger than that ofaxial strain. This shows that deformation and failure of rock is process ofevolvement of small crack. Small crack evolves from even and out-of-orderstatus to heterogeneous and ordinal status.(5) Ultrasonic speed decreases with the number of cycle. The decreasecourse is such: Firstly, ultrasonic speed fluctuates in a steady scope in somecycles; And then ultrasonic speed quickly decreases to a certain more smallvalue; Afterwards in succedent cycles, ultrasonic speed fluctuates about thevalue. That is to say, ultrasonic speed fluctuates and decreases at intervals ofcycles. In deformation process of rock, quantitative change and qualitativechange of its small crack evolvement carry through crosswise.(6) Strength and modulus of rock decrease with exponential function asscale of specimens increases.
同一表观应力下,局部点应变与表观应变相差可达2个数量级,表明宏观上均匀的岩石是具有细观特征的准脆性材料,其宏观力学行为是细观特征相互作用、放大的综合结果,而不是简单的叠加;(4)岩样轴向应变不均匀程度和横向应变不均匀程度随循环次数的增加渐进增大,但是在同一个循环内,横向应变离散系数随应力的变化波动较大,且同一循环级别下,横向应变不均匀程度大于轴向应变不均匀程度,表明岩石内部微裂纹的演化是岩石变形破坏的本质特征,这一演化表现为微裂纹从均匀无序分布逐渐向非均匀有序发展;(5)随循环次数的增加,所有岩样内部超声波速会出现衰减,衰减过程表现为在某几次循环内超声波速在某一相对范围内波动,然后急剧减小到某一较小值,在随后的循环内,超声波速又会保持在这一较小值附近波动,即超声波速表现为波动和急剧减小间隔形式衰减,表明从宏观看来平稳的岩石变形过程,内部结构演化过程(微裂纹发展及其相互作用)却表现为均匀量变和突发质变不断交叉进行的现象;(6)岩石强度和弹性模量随尺度增大呈指数函数规律减小。

The results indicate that its dynamic stress-strain curve is hyperbolic type. The dynamic strain of LCES decreases with increasing confining pressure, cement content, curing ages and cyclic loading frequency when it is subjected to the same dynamic stress. At the same dynamic strain, the dynamic secant elastic modulus E_(sec of LCES increases and the damping ratio decreases with increasing confining pressure, cement content, curing ages and cyclic loading frequency. The curves ofσ_d~ε_d,E_~ε_d and D~ε_d with different EPS content intersect respectively, the trend of LCES deformation characteristic is inversely proportional to EPS content near the intersection. The value of dynamic strain at the intersection is about 0.5%~3.0%, the magnitude of which is related to the mixing proportions and confining pressure.
试验结果表明,LCES的动应力应变骨干曲线形态符合双曲线;在相同的动应力作用下,LCES产生的动应变随着固结压力、水泥掺量、试样养护龄期和振动频率的增大而减小;在动应变相同的情况下,随着固结压力、水泥掺量、试样养护龄期和振动频率的增大,LCES的动模量增大而阻尼比减小;随着加载次数的增大,LCES的动模量在开始阶段显著降低,然后趋于稳定,但当加载次数达到几百次时,动模量又有增大的趋势;不同EPS掺入比的LCES的动应力应变骨干曲线、动模量随应变变化曲线和阻尼比随应变变化曲线都发生了相交,交点前后EPS掺入比的大小对LCES动力变形特性的影响趋势是截然相反的,交点处的动应变值一般在0.5%~3.0%范围内变化,其大小与LCES的配比以及固结压力有关。

Plastic strain stretching to failure at room temperature induced over 85% volume percent of martensite at all of tested steels. The higher cold rolled strain of steels, the smaller strain at which martensite transformation onset during stretching, but it didn't increase the saturate volume fraction of martensite.
