Removal of the membrane penetration error during evaluation of triaxial data
Open Geomechanics, 2021 Most triaxial tests are fraught with substantial membrane penetration errors. A simple correction procedure for data obtained from various tests is proposed. In particular, a correction of the undrained cyclic stress paths is presented in detail.

Indirect verification of suction in cyclic UCS tests of a chemically stabilized soil [PDF]
E3S Web of ConferencesThe present study aims to indirectly evaluate the occurrence of suction and its effects in laboratory tests of a chemically stabilized soft soil. To achieve these goals, a series of unconfined compressive strength (UCS) and triaxial tests were performed,

Comparison of Cyclic Triaxial Tests with Constant and Variable Cell Pressure
JCyclic triaxial tests are often used to evaluate the behavior of soils under seismic loads. The stress conditions imposed on a soil specimen during a cyclic triaxial test, however, are very different than those acting on an element of soil during an ...

A Novel Approach to Estimate the Transition Temperature via Dynamic Nanoindentation
Advanced Engineering Materials, EarlyView.A new dynamic nanoindentation‐based method was developed that uses the stiffness ratio as an indicator of the elastic–plastic deformation contributions at different temperatures. The approach successfully identified transition temperatures in ferritic steel and distinguished them from continuously ductile austenitic steel.

A simple method for the determination of sensitivity to density changes in sand liquefaction
Open Geomechanics, 2021 Fully saturated loose coarse-grained soils are known to be prone to liquefaction. Conventional laboratory tests for soil liquefaction include usually cyclic testing in triaxial apparatus.
