shear stiffness

Shear stiffness measurements have been taken during constant-suction tests.

A shear stiffness value of 2 (N/mm)/mm2 was given to the asphalt/base interface.

Slices from the outer and inner regions of the tuber had different shear stiffness values.

Finally, a regression analysis between the in-situ shear stiffness and pavement rutting is presented.

High shear stiffness emphasizes the phenomenon.

The shear stiffness of tubers stored for 1 month was approximately 70% greater than those stored for 10 months.

Key words : shear stiffness, nonlinearity, pressuremeter, clay.

• Further develop the "free-free beam" vibration technique for on-line evaluation of true bending and shear stiffness.

The composite has a considerably higher shear stiffness to weight ratio than an equivalent beam made of only the core material or the face-sheet material.

Simplified formulas are presented in this paper for calculating the shear stiffness and strength of metal shear diaphragms.

The results indicated that panel-edge blocking increased significantly the diaphragm shear stiffness, particularly for diaphragms without sub-floor adhesive.

Vibration techniques currently under development could provide measurement of true bending and shear stiffness, as well as axial stiffness.

The QCM allows for non-destructive testing of the shear stiffness of multi-asperity contacts.

At 0.01% shear strain, the measured average shear stiffness obtained from the extension tests was about 60% higher than that from the compression tests.

Experimental data are presented which demonstrate how shear stiffness changes with the direction of effective stress increment as a function of the ambient effective stress state.

Under cyclic DSS loading, fine-grained tailings typically exhibit a cumulative decrease in effective stress along with progressive degradation of shear stiffness.

Initial shear stiffness was measured almost continuously along various isotropic stress paths, including compressions and drying–wetting single stages or cycles, by using the RCTS cell.

An experimental study was carried out to investigate the effects of the mean net stress and suction history on the initial shear stiffness, G0, of a compacted clayey silt.

In an exploratory sequence of liquefaction tests, S-wave transillumination is implemented with a high repetition rate to provide detailed information on the evolution of shear stiffness during liquefaction.

Shear waves occur due to the shear stiffness and follows a similar equation, but with the shear deformation occurring in the transverse direction, perpendicular to the wave motion.

A design method for the calculation of shear stiffness and strength has been developed for use with the 2005 National Building Code of Canada (NBCC), however.

The influence that suction and, more in general, mean net stress – suction history has on the initial shear stiffness was analysed and ascribed to the accumulation of irreversible volumetric strains.
