Comparison of Cyclic Triaxial Tests with Constant and Variable Cell Pressure

J
Cyclic 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 ...

Some contributions to mechanical behaviors of lacustrine deposit in Bogotá, Colombia

Journal of Rock Mechanics and Geotechnical Engineering, 2019
This paper presents the mechanical behaviors of the lacustrine deposit, a representative soil in Bogotá, Colombia. Initially, the physical characterization of the deposit is performed via laboratory tests (grain size distribution, scanning electron ...

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.

Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic

Advanced Robotics Research, EarlyView.
Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these

Rate-Dependent Response of Dense Sand in Cyclic Triaxial Tests

Soils and Foundations, 2008
A number of cyclic triaxial tests were performed on Monterey No. 0/30 and Sacramento River Sand to investigate the effect that loading frequency has on the response of sands. The tests were performed on dense, air pluviated sand with loading frequencies of 0.1 and 1.5 Hz at varying confining pressures, cyclic shear stresses, and peak shear stresses ...
