DESCRIPTION

The new GCTS TRX-ROCK Advanced software is part of the CATS 32 bit Windows software, which coupled with our new SCON electronics, is the most advanced Geotechnical software available today. This software has simplified the operation of our triaxial instruments allowing the user to directly program test calculated parameters in the units of interest (stress, strain, etc.) based on the specimen dimensions. These parameters are calculated in real time and are available for control, display and/or graph.

Example of test calculated parameters includes σd - Deviator Stress, εa - Axial Strain, εr - Radial Strain, εv - Volumetric Strain, Poisson’s Ratio, Tangent and Secant Modulus, etc. (the TRX module contains 20 test inputs). The strains can be calculated from direct deformations inputs, or can be calculated as functions of each other – the selection is user selectable.

This software includes an automatic procedure for setting the initial ram contact with the specimen. The ram is first moved in deformation control while monitoring the axial stress. As soon as the ram gets in contact with the specimen, the system automatically switches to axial stress control preventing premature sample failure. This program also calculates the force exerted on the ram by the confining pressure and automatically corrects the axial load required to maintain the deviator stress and thus preventing the ram from lifting while changing the cell pressure.

The Static Loading stage is easy to setup and allows the user to perform static loading on the specimen while allowing the user to change the stress and or strain rates for all of the controlled axis (Axial, Cell Pressure and Back Pressure) during testing. The Dynamic Loading Stage allows the user to easily setup a dynamic loading on the specimen. If none of the predefined stages fit the needs of the user, the user can run a Universal stage on the specimen. The Universal stage of the TRX Advanced software is a very versatile and powerful module that allows the user to establish any custom test procedure that they wish. It allows the user to simultaneously and independently control the three axis outputs in the test program.

The GCTS Triaxial testing systems have been designed to take full advantage of our new software and electronics so that all test stages can be automatically performed from beginning to end with minimal user intervention.
