Measurement Systems

Gleeble systems are available in several models, each with a wide variety of available options and configurations. This flexibility allows the tailoring of a Gleeble system to meet your exact testing requirements. DSI offers a range of measurement systems including contact and non-contact options.

Below are some of DSI's most popular measurement options:

Scanning Non-Contact Optical Dilatometer and Extensometer with Green LED Technology

LED

Optical System Achieving High-Speed, High-Accuracy, and High-Durability.

The system uses a high intensity GaN long life LED combined with an HL-CCD sensor to provide high speed measurements with no moving parts. This unit has twice the speed of conventional laser based measuring units. Easy to use menu driven setup software is included with the unit to allow configuration of the controller on the desktop PC. A unique tracking system ensures measurements are taken in the correct plane.

This optical system is available on Gleeble 3500-GTC and Gleeble 3800-GTC systems, including the Gleeble 3800-GTC-20/20.

Green LED

More Accurate and Easier to Use: Green LED technology achieves both quick and accurate measurement reliably and durably.

Digital Image Correlation Systems

Digital Image Correlation (DIC) is a 3D, full-field, non-contact optical technique that can be used in conjunction with Gleeble systems for precise measurements of deformation and strain on many specimen geometries.

DSI has developed a successful combination of high performance cameras, lighting, mounting and licensed software to produce accurate results, even at elevated temperatures (up to 1,200°C).

Digital Image Correlation can be utilized on a number of standard Gleeble tests including tensile tests, Strain Induced Crack Opening (SICO), flow stress compression, as well as other standard and custom simulations.

DIC systems provide full field measurements across a specimen allowing characterization of strain fields in an entire test region. Traditional contact measurement systems provide only 2-point strain measurements – from one point to another point.

Contact Measurement Systems

DSI offers a range of highly accurate contact extensometers that can be utilized for a variety of measurements, both crosswise and lengthwise on wide range of specimen types, both in and out of the specimen’s hot zone. Both LVDT and strain gauge measurement systems are available. These components have been designed to be easy to install and operate. Some of the more popular systems are listed below:

39060 - Hot Zone L-Strain:
An LVDT type hot zone transducer commonly, used for tensile tests or simulations with large amounts of deformation in tension or compression. (25mm travel)

39071 – Hot Zone L-Strain:
A strain guage type hot zone
transducer, commonly used for
tests requiring high resolution with small amounts of travel. (5mm of travel in tension, 2mm of travel in compression)

39010 C-Gauge:
Crosswise LVDT type gauge with large travel (12mm) measures significant deformation.

39018 Dilatometer:
Highly accurate and reliable, the Dilatometer is commonly used to generate CCT/TTT data.

Dr. Hans Peter Schmitz

ThyssenKrupp Stahl

“ In our labs, we do physical simulation… We try to reproduce as precisely as possible what is going on in the actual production lines. If you do it very carefully, you can transfer the result into the production lines, and you can use the results for building up numerical models."

Dr. Leijun Li

Utah State University

"On the Gleeble we can not only control all the mechanical properties, but we’re in command of the thermal properties and the atmosphere. With the Gleeble, we can do complicated applications, watch what is happening, see the effect of temperature, and know how much energy is going in. It would take a lot more time and money to do it with equipment other than the Gleeble."

Dr. Luis A. Colembergue Klujszo

Gerdau Aços Especiais Piratini

"Through the capability of simulating large scale, expensive processes in a small scale, laboratory environment, the Gleeble has made it easier for Gerdau to improve products and processes. Furthermore, all the controls available in the equipment bring a whole lot of reliability to the results, making the conclusions very sound."

Tom Schambron

Bluescope Steel

"…world research and innovation are cornerstones of our business - the Gleeble is key to meeting the objectives of BlueScope. It assists in product development and improvement—such as trialling new steel grades, processing parameters, and so forth—and in tracking and solving of quality issues."

Dr. John Bowker

Former Senior Research Scientist CANMET Materials Technology Laboratory (CANMET-MTL)

"The Gleeble is one of the most heavily used machines at our lab... We have used and continue to use it for a broad range of thermo-mechanical simulation procedures. These include: welding applied to shipbuilding, marine materials, offshore structures and pipelines; compression testing to characterize the flow stress behavior of steels and aluminum alloys: and in situ melting and solidification to understand the effects of residuals on hot ductility."

Dr. David Matlock

Colorado School of Mines

"Flexibility is the key to our extensive use of the Gleeble. It helps us to get maximum productivity out of the work we do."

Dr. Mahesh Chaturvedi, Ph.D., FASM

University of Manitoba, Department of Mechanical and Manufacturing Engineering

“We want to understand what the fundamental causes for thermo-mechanical fatigue are, so we use the Gleeble to apply load and temperature, sometimes in sync and sometimes out of sync. The Gleeble can keep going for days, executing the same program again and again... it gives us excellent reproducibility.”

Dr. Arnold Marder

Energy Research Center, Lehigh University

“What we are aiming at is intelligent processing. That’s where the Gleeble gives us a tremendous advantage. By allowing us to carefully simulate and model thermal and mechanical processes”

Damien Fabrègue

The Institut National des Sciences Appliquées (National Institute of Applied Science) de Lyon, Villeurbanne, France

"...this is the only piece of equipment that I can do everything with. I can always do what I want. It may take some time to optimize the work, but in the end, you can always run the experiment or do the simulation that you wanted to do."

Dr. Hirowo Suzuki

Nippon Steel (retired)

“In my opinion, Dynamic Systems is the top company in this kind of test equipment… worldwide.”

Dr. Warren Poole

University of British Columbia

"We had to generate all the parameters and then to validate the predictions that the computer model made… The Gleeble played a central role in that project. We did austenite grain growth studies, double-hit compression tests to study recrystallization, and continuous cooling transformations, with and without compression."

Chihiro Kasamatsu

Material Evaluation Department Aichi Steel Corporation

“…we are concentrating on testing with the Gleeble to reduce costs in our forging production processes…”

Dr. Brian Damkroger

Los Alamos National Laboratory

"Only the Gleeble is fast enough to allow us to physically simulate the thermal profile of electron beam welding”
