Similar to [DELTA][sigma], [DELTA][[sigma].sub.d] increases with the increase in [[sigma].sub.1d] (deviator
stress) under the air-dried and wet conditions.
where [epsilon.sub.p] is cumulative soil plastic strain, N is the number of repeated stress applications, [sigma.sub.d] is soil deviator
stress caused by train dynamic load, [sigma.sub.s] is soil compressive strength, a, m, b are parameters dependent on soil type.
Where [e.sup.evK.sub.ij] is viscoelastic Kelvin value, [e.sup.evM.sub.ij] is viscoelastic Maxwell value, [S.sub.ij] is deviator
stress tensor, G is shear modulus, [eta] is dynamic viscosity.
The peak deviator
stress is correspondingly increasing at higher effective confining stress as shown in Figure 3(b).
The resilient modulus represents the ratio of repeated deviator
stress to recoverable lateral strain, based on the results of constant confining-pressure triaxial tests.
The strain deviator
of nonlinear elastic material take the form
These strategies are based on the threat to punish a deviator
at the moment his deviation from the agreed upon trajectory has been detected.

Figure 6 shows a typical set of results from this research for a CIU cyclic triaxial tests data regarding on an Ottawa sand sample; this figure shows three plots representing deviator
stress, excess pore pressure, and axial strain measurement as a function of number of load cycles.
2007); [[sigma].sub.d] - the deviator
stress, kPa; [k.sub.w] - (-0.1417) to Coarse - grained soil, [k.sub.w] - (-0.0574) to fine-grained soil; w - moisture content, %; [w.sub.opt] - optimum moisture content, %.
The fig ure illustrates that the dry funnel pluviation method gives rise to more significant values of the maximal deviator
and consequently much higher resistance to liquefaction, while the wet deposition method yields weaker values of the maximal deviator
, with progressive stabilization around a very weak or ultimate stationary value of zero indicating liquefaction of the sample.
