  sliding strain
Using this model, an expression for the stress and temperature dependence of the total steady state strain rate is obtained as a function of the grain matrix strain rate and the grain boundary sliding strain rate.
      
If diffusional process is not sufficiently fast to accommodate sliding strain, especially at high strain rates.
      
  sliding stress
The stress/time, sliding/time and sliding/stress curves for these tests are presented together with metallographic observations.
      
The temperature-dependence of the sliding behaviour, as reflected by the sliding/stress results, yielded apparent activation energies of ~ 31 Kcal/mole in the temperature range 600 to 475°C and ~ 8 Kcal/mole in the range 475 to 350°C.
      
While the frictional sliding stress appeared to be independent of the fabrication technique, the interfacial debond shear stresses were larger for the DS composites compared to the PC composites.
      
The postdebond sliding stress was higher in sapphire-NiAl(Cr) than in sapphire-NiAl(W) due to interface enrichment with chromium particles.
      
In addition, independent measurements of the sliding stress have been made using fiber pushout tests on both pristine and fatigued specimens.

  slip stress
The Marmara region, located near the western end of the NAF, is a tectonically active zone characterized by the transition between a strike slip stress regime and an extensional one in the Aegean Sea.
      
For fcc metals, correlation of the H-P slope with the cross-slip stress, predicted by the Armstrong model, has been demonstrated for a few cases.
      
Quartz gouge between the pre-cut surfaces of Tennessee Sandstone lowers both the kinetic coefficient of friction and the magnitude of the stick-slip stress drops compared to those for a pre-cut surface alone.
      
Stick-slip stress drops are preceded by stable sliding at displacements of 10-5 cm/sec.
      
The interaction between a fault segment and its neighboring segments can be measured when the post-slip stress on this segment is compared with the stress on an identical segment (represented by a block in this modeling) without neighboring segments.

The Ae response of granite during fracture and friction was measured at high confining pressure up to 600MPa. The first active region of AE signatures in uniaxial testing was not found when confining pressure was loaded. The AE response shows a transition from dense to dense-unstable as confining pressure increases. The curvature of the increasement of cumulative AE events during deformation decreases with increasing of confining pressure. Filling the data with exponential function, it is found that the exponential...

The Ae response of granite during fracture and friction was measured at high confining pressure up to 600MPa. The first active region of AE signatures in uniaxial testing was not found when confining pressure was loaded. The AE response shows a transition from dense to dense-unstable as confining pressure increases. The curvature of the increasement of cumulative AE events during deformation decreases with increasing of confining pressure. Filling the data with exponential function, it is found that the exponential coefficients decrease and the discrepancy of AE activity among deformation stages decreases and dis appears with increasing of confining pressure. The AE response during accumulation of stress of friction sliding obeyed the exponential law too, but the exponential coeffcient was lower than that of fracture of intact sample. The AE events increase simply with sliding distance during stable sliding.

在600MPa范围内,实验测定了居庸关花岗岩变形破坏和摩擦滑动过程中的声发射活动性。在有围压的情况下,岩石变形破坏过程中缺少在单轴压缩下经常出现的第一次声发射活动高峰;随着围压的增加,声发射活动性由致密型向致密不稳定型过渡;开始出现声发射所对应的应力—应变条件相对于破裂点而言有随围压增加而“提前”的趋势.采用归一化的处理以后,发现破裂过程中声发射累计数增长曲线随着围压增加而曲率减小。指数函数拟合结果表明:随围压增加指数系数减小,并且阶段间的差别逐渐消失。摩擦滑动的应力积累阶段的声发射活动性也遵循指数规律上升,但指数系数较变形破坏过程为小.稳定滑动过程本身的声发射累计数随应变量的增大只是线性地增加.

在已有的基于膨胀体模型、动理论模型和连续介质理论得到的关系式基础上,分析了水沙流中颗粒流动的应力关系应由摩擦应力、滑动应力和碰撞应力3部分组成,并将颗粒弹性恢复系数引入,对颗粒碰撞项进行了修正。根据颗粒碰撞时间间隔T_c和颗粒弛豫时间T_e的对比,提出了颗粒流动进入碰撞惯性区的临界值,即当T_c/T_e<0.02时,水沙流中颗粒流动碰撞作用占优,可忽略摩擦应力和滑动应力,并将提出的临界值与实验资料进行了比较。利用修正后的水沙流中颗粒流动应力关系,对缓槽水沙流动进行了模拟计算,获得了与实测资料一致的结果。
