Gleeble - Model 3500-GTC -Thermal-Mechanical Physical Simulation System
The Gleeble 3800-GTC System is designed to meet the demanding requirements of modern research applications, offering both versatility and high performance. This system includes the Gleeble Touch Control (GTC) console, a Windows workstation, a load unit with a test chamber, and a hydraulic power supply. Its direct resistance heating system can heat specimens at rates exceeding 10,000°C/sec, with precise temperature control via thermocouples or an optional infrared pyrometer. The system also supports high cooling rates with its water-cooled jaw carriers and optional quench system. The mechanical system is capable of exerting up to 20 tons of static force in compression and 10 tons in tension, with stroke displacement rates programmable up to 2,000mm/sec. Feedback control is ensured through Linear Variable Differential Transformers (LVDTs), providing accurate and repeatable test results. The integrated software allows for full control and customization of testing protocols, accommodating various thermal-mechanical processes. An optional induction heating system can be added for uniform temperature control in specific testing scenarios.
Offering versatility and performance for today's demanding research and production applications.
With the introduction of the Gleeble 3500-GTC, Dynamic Systems Inc. has once again raised the standard by which all thermal-mechanical testing machines and physical simulation systems are judged.
The Gleeble 3500 is a fully integrated digital closed loop control thermal and mechanical testing system. Easy-to-use Windows based computer software, combined with an array of powerful processors, provides an extremely user-friendly interface to create, run and analyze data.
The Gleeble 3500 Thermal System
The direct resistance heating system of the Gleeble 3500 can heat specimens at rates of up to 10,000°C/second, or can hold steady-state equilibrium temperatures. High thermal conductivity grips hold the specimen, making the Gleeble 3500 capable of high cooling rates. An optional quench system can achieve cooling rates in excess of 10,000°C/second at the specimen surface.
Thermocouples or an optional infrared pyrometer provide signals for accurate feedback control of specimen temperatures. Because of the unique high speed heating method, Gleeble systems typically can run thermal tests 3 to 10 times faster than conventional furnace equipped machines.
The Gleeble 3500 mechanical system is a complete, fully integrated hydraulic servo system capable of exerting as much as 10 tons of static force in tension or compression. Displacement rates as fast as 1000 mm/second can be achieved. LVDT transducers, load cells, or non-contact laser extensometry provide feedback to insure accurate execution and repeatability of the mechanical test program.
The mechanical system allows the operator to program changes from one control mode to another during any given test. This capability provides the versatility that is necessary to simulate many thermal-mechanical processes. The program can switch between control variables at any time and as often as required during the test. Control modes that are available include stroke displacement, force, various extensometers, true stress, true strain, engineering stress, and engineering strain.
Induction Heating Option: Gleeble 3500-GTC and 3800-GTC systems can be supplied with an optional Induction Heating system to complement the industry leading performance of the well-known Gleeble direct resistance heating technology.
Induction heating is suited for use in uniaxial compression testing (flow stress) where it can provide a uniform temperature across the specimen from anvil to anvil. Induction heating can also be used in tensile testing. The system allows the user to select either induction or resistance heating based on the needs of each specific test. The full capability of the high speed Gleeble direct resistance heating system is still maintained, allowing heating rates up to 10,000ºC/second when using direct resistance heating. The two heating systems are both integrated to work on the Gleeble and software can be used to select which heating system is used in each test.
