Soil liquefaction as an identification test [PDF]

E3S Web of Conferences, 2019
Time-consuming and complicated investigations of soil liquefaction in cyclic triaxial tests are the most common way of laboratory analysis of this phenomenon.

Comparison of sand liquefaction in cyclic triaxial and simple shear tests

Soils and Foundations, 2021
The liquefaction resistance and correction factors Kσ and Kα of Nakdong River sand obtained from cyclic triaxial (CTX) tests were compared with those determined by cyclic simple shear (CSS) tests to ascertain the importance of the reduction factor Cr and

Triaxial compression tests on a crushable sand in dry and wet conditions [PDF]

, 2015
A calcareous sand from the Persian Gulf is subjected to a series of dry and fully drained saturated triaxial shear tests. The samples are prepared at relative densities of 65% and either left dry or saturated. They are consolidated to confining pressures

Analysis of a rapid load test on an instrumented bored pile in clay [PDF]

, 2006
Rapid load testing methods for piled foundations are generally easier and quicker to mobilise than classic static tests, and are less complex to analyse than dynamic load tests.

MELEGROS: Monolithic Elephant‐Inspired Gripper with Optical Sensors

Advanced Science, EarlyView.
MELEGROS is a monolithic, elephant‐inspired soft gripper integrating 3D‐printed optical sensors within a pneumatically actuated lattice. Simulation‐guided design decouples tactile and proprioceptive sensing. Characterized through grasping tests, MELEGROS can reach, scoop, and grasp, showcasing a paradigm where fully embedded sensing and continuous ...
