The extensive application of natural unbound granular materials (UGMs) motivates studies into the mechanical properties alternatives such as processed crushed rocks employed commonly base or subbase layers. rutting and settlement generated in layers is widely restricted many specifications standards. In this research, dynamic behavior including resilient modulus (Mr) plastic strain (??p) collec...

The present study concerns compressive and flexural constitutive models incorporated into an isoparametric beam finite element scheme for fiber reinforced polymer (FRP) and concrete composites, using their multi-axial constitutive behavior. The constitutive behavior of concrete was treated in triaxial stress states as an orthotropic hypoelasticity-based formulation to determine the confinement ...

called maximum shear modulus, Gmax. It can be determined by in-situ methods from the measurements of the shear wave velocity, Vs, by means of crosshole, down-hole, up-hole, or surface wave testing. The relationship between maximum shear modulus and shear wave velocity is rigorous: 2 max s G V    where ρ is soil density. This parameter can be also obtained in laboratory by resonant column or ...

Previous studies have revealed that prefabricated vertical drains (PVDs) are effective in stabilizing the soft subgrade soils under traffic-induced cyclic loads. A consolidation model of clays loading incorporating both radial and drainages, nonlinear variation compressibility permeability is presented this paper. The prediction matches well with result from a large-scale triaxial test conducte...

Abstract When specimens of different sands are produced using the same preparation method and sheared under conditions (consolidation stress, loading, etc.), while simultaneously keeping drainage closed, resulting tendencies these regarding PWP build-up will be different. This research paper presents a simplified cyclic shear test, which is used to evaluate accumulation in defined specimen proc...

Compaction in sedimentary basins has been traditionally regarded as a one-dimensional process that ignores inelastic deformation directions orthogonal to the active load. This study presents new experiments with sandstone demonstrating role of three-dimensional compaction cyclic true triaxial compression. The were carried out on basis independent loading test system Laboratory Geomechanics Ishl...

We present a simple method, based on the deformation of spherically symmetric potentials, to construct explicit axisymmetric and triaxial MOND densitypotential pairs. General guidelines to the choice of suitable deformations, so that the resulting density distribution is nowhere negative, are presented. This flexible method offers for the first time the possibility to study the MOND gravitation...
