Testing and Data Acquisition/Control Equipment for Soil Dynamics and Geotechnical Centrifuge Laboratory

Abstract

A description of equipment purchased under an AFOSR equipment grant is provided. This equipment is being used to extend the capabilities of the existing MTS servohydraulic axial-torsional testing machine to allow high precision tests on hollow cylinder soil specimens at constant mean stress levels, especially for specimens undergoing very small strains. The principal equipment items acquired are a computer based data acquisition and control system, a new hollow cylinder triaxial cell, a number of transducers and associated electronics, and mechanical hardware, including a new hydraulic power supply. In addition, several equipment items have been acquired with the RPI matching funds for the existing 100 g-ton geotechnical centrifuge, including a container for holding models during testing and a fork lift for model transport. Keywords: Laboratory/test equipment; Soil mechanics; Hollow cylinder tests; Data acquisition and control system; Geotechnical centrifuge; Soil dynamics.
