This paper presents the results of an investigation into the potential application of rubber-modified asphalt in railroad trackbeds by measuring its shear modulus and damping ratio. The measurements of the shear modulus and damping ratio were also conducted on typical subgrade soils. A number of res...
Carbon nanotubes are believed to be the ultimate low-density high-modulus fibers, which makes their characterization at nanometer scale vital for applications. By using an atomic force microscope and a special substrate, the elastic and shear moduli of individual single-walled nanotube (SWNT) ropes...
A torsion pendulum has been used to measure the shear modulus of a range of polymers as a function of applied hydrostatic pressure at 20° C. The pressure medium was usually nitrogen gas and the maximum pressure 20000 psi. The results show that the shear modulus of each polymer is increased...
The shear modulus of these single layer graphene films are about five times higher, averaging 280 GPa. Their low temperature internal friction is too small to measure within the uncertainty of our experiments. Our results demonstrate the dramatic difference in the elastic properties of multilayer and...
Resonant column tests involving anisotropic confining conditions were conducted to evaluate static stress condition, especially stress ratio effects on the lowamplitude dynamic shear modulus,G0,of three clean, dry sands. Six static stress paths, involving both triaxial compression and triaxial extension, ...
This paper presents a simple empirical equation for the calculation of the post-cracking shear modulus, given in the form of the tangent slope of the shear stress–strain curve. The proposed empirical equation is based on the experimental results from forty membrane specimens, and relates the ...

A unified 3-d critical state bounding surface plasticity model (gUTS) has been developed which is able to provide realistic simulations of the behavior of clays, silts and sands both in drained and undrained conditions over a wide range of monotonic and complex cyclic paths. A strong feature of...
The experimental values available in the literature for the shear modulus, the bulk modulus and Young's modulus of polycrystalline f.c.c., b.c.c. and h.c.p. metallic elements were critically evaluated. It was shown that simple relations exist between the elastic moduli of polycrystalline meta...
This work presents new developments in resonant torsional tests in order to determine the shear modulus G of bulk and coated materials. For this purpose, two main problems are resolved: free vibrations in torsion mode are obtained on rectangular plate samples maintained elastically between crossed wi...
