Stress path during pressuremeter test and link between shear modulus and Menard pressuremeter modulus in unsaturated fine soils

Nonlinear modeling of soil deformation modulus through LGP-based interpretation of pressuremeter test results

Soil deformation modulus is an essential parameter for the analysis of behavior of substructures. Despite its importance, little attention is paid to developing empirical models for predicting the deformation moduli obtained from the field tests. To cope with this issue, this paper presents the development of a new prediction model for the pressuremeter soil deformation modulus utilizing a line...

Predictive Model for Normalized Shear Modulus of Cohesive Soils

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 ...

The Validity Assessment of Laboratory Shear Modulus Using In-Situ Seismic Piezocone Test Results

Seismic piezocone device (SCPTu) together with Resonant Column and Cyclic Triaxial test apparatus are employed to measure small strain shear modulus (G0) of carbonate sandy and clayey soils of southern coasts of Iran. A large area of southern regions of Iran is formed from clay, silt and sand. In this study, maximum shear modulus that is derived from both field (by seismic piezocone) and labora...

A Test Method for the Determination of Shear Modulus and Shear Strength

Thi« report presents a method for determining shear modulus and shear strength of unidirectional flber-relnforced composites. The method Incorporates data from unlaxlal tensile and/or oompresslve tests at fiber orientations of 0, 45, and 90 degrees. The approach presented requires fewer specimens for shear strength determinations than current exlstinc procedures. ^ Distribution of this abstract...
