A Novel Preparation Device for Remolded Hollow Cylinder Specimen of Frozen Soil

Springer Series in Geomechanics and Geoengineering, 2018
The frozen soil hollow cylinder apparatus is the main experiment instrument to study the mechanical behaviour of frozen soil under complex stress paths including stress rotation. However, it is difficult to prepare hollow cylinder specimen due to the thin wall.

Investigation of fatigue strength under wide-ranged biaxial stress for two types of stainless steel using a thin-walled hollow cylinder specimen

International Journal of Fatigue, 2020
Abstract Stress-controlled multiaxial fatigue tests were carried out by using hollow cylindrical specimens of type 430 and type 316 stainless steel at room temperature. A recently developed fatigue testing machine, which can apply push-pull loading and inner pressure to the specimen was used.

A three-dimensional soil–water coupled FE analysis of hollow cylinder test concerning non-uniform deformation [PDF]

Soils and Foundations, 2013
The hollow cylinder shear test is somewhat controversial due to its non-uniform stresses and strains, and has been analyzed by simple theoretical methods and two-dimensional FE calculations.

Stress Nonuniformities in Hollow Cylinder Torsional Specimens

Geotechnical Testing Journal, 1991
Abstract Stress nonuniformities across the wall of hollow cylindrical torsional shear (HCT) specimens under generalized stress conditions are assessed taking into account the nonlinearity in soil behavior. The domain of stress space that results in acceptable levels of nonuniformities is thus delineated for a given specimen geometry.

Novel Method for Characterizing the Mechanical Properties of the Cement Sheath Based on Hollow-Cylinder Specimen and Multiaxial Load Tests

SPE Journal, 2022
Summary Mechanical properties such as Young's modulus, Poisson's ratio, and strength are important parameters for evaluating the cement sheath integrity. However, the current triaxial testing methods for the mechanical properties of intact-cylinder cement specimens ignore the “ring” shape of the wellbore cement sheath and its nonuniform ...

Comparison of True Triaxial and Hollow Cylinder Tests on Cross-Anisotropic Sand Specimens

Geotechnical Testing Journal, 2014
Abstract Experiments have been performed in true triaxial equipment and in hollow cylinder equipment on dense Fine Nevada sand to study and compare the influence of the intermediate principal stress on the behavior observed in the two types of apparatuses.

The Preparation of Hollow Cylinder Specimens from Undisturbed Tube Samples of Soft Clay

Geotechnical Testing Journal, 1990
Abstract The use of torsional-hollow cylinder testing apparatus for research into soil stress-strain behavior has grown over the past decade. Most studies have focused on sands or on cohesive materials reconstituted in the laboratory. Studies involving undisturbed soft clay have been neglected, in part due to the difficulties involved in
