Specimen Preparation Methods for Artificially Cemented Sand in Simple Shear and Hollow Cylinder Apparatuses [PDF]

open access: yesScientia Iranica, 2017
Portland cement can be mixed with sand to improve its mechanical characteristics. Considering the inherent anisotropy of most sands, it is not clear whether the added cement shall contribute to equal increases of strength and stiffness in vertical and horizontal directions or not.

Experimental study on sand anisotropy using hollow cylinder apparatus

open access: yesSoils and Foundations, 2023
This study investigated sand anisotropy experimentally using a hollow cylinder apparatus. The effect of the initial anisotropy on the shear behavior of sand was illustrated by conducting experiments on specimens with bedding planes and systematically ...

A Critical Assessment of Stress Nonuniformities in Hollow Cylinder Test Specimens

open access: yesSoils and Foundations, 1991
A critical assessment of stress nonuniformity in hollow cylinder torsional specimens used in the study of soil behaviour under general stress paths is presented. It is shown that acceptable levels of nonuniformity in individual stress components adopted in earlier studies can cause serious and unacceptable nonuniformity in stress ratio across the ...

Fatigue Testing and Evaluation of Fatigue Strength under Multiaxial Stress State; Why do we need fatigue testing?

open access: yesMATEC Web of Conferences, 2018
Types of multiaxial fatigue tests and their experimental results are presented in this paper. There are typical three types in multiaxial fatigue tests: the combining push-pull and reversed torsion loading test using hollow cylinder specimen, the biaxial

PCA Based Stress Monitoring of Cylindrical Specimens Using PZTs and Guided Waves

open access: yesSensors, 2017
Since mechanical stress in structures affects issues such as strength, expected operational life and dimensional stability, a continuous stress monitoring scheme is necessary for a complete integrity assessment. Consequently, this paper proposes a stress
