Effects of end restraint in triaxial tests on coarse-grained soil

open access: yesYantu gongcheng xuebao, 2017
The end restraint can be eliminated by lubrication sample cap to some extent in the conventional triaxial tests. A comparison is made between the conventional triaxial tests and the end friction reduced triaxial tests in order to study the effects of the

Use of Acoustic Emissions to Validate Multistage Triaxial Tests—A Key to Characterizing the Subsurface

open access: yesInfrastructures
Acoustic emission (AE) measurements have many uses to evaluate the integrity of materials. AE is often used to detect leakage in pipelines. It has also been used to monitor changes in strength properties of fiber-reinforced concrete.
