Since the stress-strain curve of the cemented sand artificial material is nonlinear and changes more significantly with increasing stress (strain), the elastic modulus is correlated with the selected reference points. Many parameters can be described, such as initial modulus E I, secant modulus E s, tangent modulus E t, and mixed modulus E [26 ...

The effective modulus of plasticity is generally lower than the shear modulus of the elastic region (i.e., 0 < g(γ) < G, where G is the shear modulus of the elastic region). In case of homogeneous PMMA the ratio of shear modulii for elastic and plastic regions appears to be in the order of 5 (see Figure 1). We therefore simulated the initial ...

N/mm2 (v) Elastic Deformation. The modulus of elasticity is mainly dependent on the elastic properties of the aggregate and to lesser extent on the conditions of curing and age of the concrete, the mix proportions and the type of cement. The modulus of elasticity is generally associated with the compressive characteristic strength of concrete.

The elastic modulus obtained in the laboratory using plate load test is in the range 20 to 24 MPa. This value is reasonably confirming with the range of modulus of elasticity mentioned in the literature (Bowles). Study reveals that, for different values of Poisson's ratio of sand (0.3 to 0.45), modulus of elasticity varies between 14 to 16 %.

sand grains, Fused Silica has amorphous molecular structure and this structure can result in lower Elastic modulus as well as compressibility to up to 20% under compression loadings. This behavior can also be seen in granular material such as powders or geomaterials. Soils also do not bear tensile stress but can show higher strengths when

For normal incidence propagation perpendicular to the layers, the effective P-wave modulus is given by a volumetric harmonic average of the sand and shale moduli. The effective density is given by the usual volumetric arithmetic average of sand and shale densities. By doing the

In many parts of the world, dams, hydroelectric power plants, tunnels, and highways have to be built in the regions where the weak rocks are dominant. In the solution of the above-mentioned geotechnical design problems, the elasticity modulus is an important parameter to be found. However, it is quite difficult to find the elastic modulus (E) values of highly porous low-strength rocks with ...
