Comparison between results of dynamic static moduli of#0183;Results are used to further investigate and compare the controlling mechanisms and trends in changes of dynamic bulk modulus and static Youngs modulus of the sand layer.The static Youngs modulus depends on the stress history and increases significantly for over-consolidated samples,while the dynamic bulk modulus is more related to the Some results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456NextSome results are removed in response to a notice of local law requirement.For more information,please see here.12345NextA comparative study of the anisotropic dynamic andgranite samples,dynamic moduli were twice the static moduli at 0 MPa and did not become approximately equal until confining pressures of 300 MPa were reached.Similar results were obtained on sandstone,limestone oil shale,and biotite schist samples by Cheng and Johnston (1981) and King (1983).Wong et al.(2008) observe that,at 6 MPa

Relations between static and dynamic moduli of

difference between static and dynamic moduli; however,it depends on the actual static deformation rate and the fre-quency of the elastic waves applied.If the static and dynamic strain rates are equal,strain rate can be eliminated as a cause for difference between static and dynamic moduli.This is theModeling of stress-dependent static and dynamicdifference between the static and the dynamic moduli as failure is approached.The simulations thus support the assumption that theoretical insight in the grain-scale deformation mechanisms helps to understand and explain the difference between static and dynamic moduli,asEstimation of Elastic Moduli of Particulate Composites by The comparison between the theoretical values of ,as they result from models 2,3,and 4,and the experimental values of ,can be done taking into account the following facts.(a) In [] it is mentioned that model 1 corresponds to high adhesion quality between matrix and filler and that model 2 corresponds to low adhesion quality while in [] it is mentioned that models 3 and 4

Effects of stress cycles on static and dynamic Young's

This result is based on a series of stress-cycling measurements on room-dry Castlegate sandstone (UCS = 16 MPa) where we have made simultaneous measurements of both the static stress-strain behavior and the dynamic sound speeds (P and S) on the sameDynamic and static measurements of small strain moduli of Consequently,the dynamic moduli of denser specimens were larger than the static moduli by about 20 %,while the difference between the dynamic and static moduli of the looser one became as larger as 60 %.Figure 13 Comparison between P wave and S wave measurements .Figure 14 Time-history data from P wave measurement in the test AC80Differences between static and dynamic elastic moduli of a Apr 01,2004 Comparison between results of dynamic static moduli of#0183;The proposed empirical relations show that values of static moduli appear to be in general 5 to 10 per cent lower than those of dynamic moduli.The scatter among the data is very large and in some cases values obtained from static measurements can be smaller than those from dynamic estimates by as much as an order of magnitude.

Correlation between dynamic and static bulk moduli of

We studied the continuous evolution of static and dynamic bulk moduli of a porous sandstone (Bentheim sandstone) with isotropic stress under different hydromechanical conditions.The static bulk moduli were achieved from the analysis of the stress-volumetric strain curve while dynamic bulk moduli were derived from the changes in ultrasonic P- and S-wave velocities along different traces which Comparison between results of dynamic static moduliThe difference between static and dynamic loading is that the second induces very small shear strain less than the elastic strain of 0.001%,while shear strains for static loading of foundations are generally in the range of 0.10.01% [2].Several studies have shown that the shear modulus decreases dramatically with increasing shear strain.Comparison between results of dynamic static moduli of Comparison between results of dynamic static moduli of soil determined by different methods
