GCTS Testing Systems

GCTS was founded in Arizona (USA) in 1994 and has been manufacturing World Class Test System’s since then…They now have a very comprehensive range of testing solutions for advanced material characterisation.

They manufacturer test systems for: Soils, Rock, and Asphalt. Using: Pneumatic, Hydraulic, or Electromechanical Pressure Loading Systems.

Each System comes with an advanced Software Package for: Test Control, and Data Acquisition.

GCTS has a strong global presence and employs a team with a vast engineering experience.

You have a large range of test systems to choose from and these can be off the shelf type systems, or tailor made to meet your testing requirements.

Vtech Materials Testing Equipment has been working with GCTS since 2010 and has a very strong working relationship with them…We have supplied a large number of systems to the majority of major Universities and Commercial Testing Laboratories across Australia.

Vtech works closely with GCTS and the Customer through the enquiry and quotations stages. Then handles the purchase order, Export of the goods from the USA via Air or Sea Freight, Customs Clearance, and local Delivery.

Should the purchase include an Installation & Training Package…Vtech works with the GCTS Engineer and Customer to ensure that this happens promptly and effectively.

Hollow Cylinder Test

The GCTS Hollow Cylinder Testing Systems are capable of performing advanced tests on large, hollow soil specimens, including liquefaction, plane strain, simple shear, dynamic shear strength, and shear modulus. These systems are able to simulate most field stress and strain paths and can perform both static and dynamic tests. By providing digital servo control of axial load, torque, confining pressure, internal pressure, and back pressure, the GCTS Hollow Cylinder Testing Systems are capable of subjecting the soil specimen to any stress state and follow any stress/strain path.

The included software automatically controls all five axes and calculates more than 20 HCA test parameters in real-time that can be used as control feedback to prescribe an infinite number of stress/strain paths. This includes the principal stress angle (α), allowing the system to easily prescribe the rate and magnitude of the σ1 rotation.

The system manages all the instrumentation and continuously monitors sensor outputs to accurately account for uplift pressures acting on the loading piston, area changes, deformation and volume change sensor setup, re-positioning, and more. It also advises the user on how to perform testing tasks and reminds the user of important steps in the test, which helps to minimize the learning time and ensure laboratory personnel can conduct tests with minimal error.
