Low Cycle Fatigue (LCF)
The aerospace, automotive, and power generating industries have all contributed to the rapid growth of Low Cycle Fatigue (LCF) testing as a subfield of materials science. Strain controlled fatigue testing, commonly used to mimic mechanical stresses into the plastic region, is governed by the ISO 12016 and ASTM E606 standards. The high temperatures used in these tests are meant to mimic the conditions under which turbine blades in gas turbines and jet engines will operate in service.

Features:
-    High capacity loading frame maximizes lateral and axial stiffness during reverse stress testing.
-    Optional backlash free, all-electric actuator delivers precise slow speed control with virtually silent operation and no hydraulic infrastructure requirements.
-    AlignPRO alignment fixture and supporting software are provided as standard to ensure precision loadstring alignment.
-    Three zone furnace with cascade control of specimen temperature with optimized temperature gradient.
-    Dedicated LCF3 software suite provides streamlined test setup and analysis of hysteresis loops, plastic strain measurement and common LCF calculations.
-    All Instron LCF systems are fully integrated and are supplied ready to test, meeting all appropriate international standards.

Electro-Thermal Mechanical Testing (ETMT)
Testing miniaturized specimen with direct resistance heating

Accelerating high-temperature research can be conducted with the help of the Instron Electro-Thermal Mechanical Testing instrument (ETMT), a small testing instrument designed for use on a tabletop. With heating and cooling speeds of 200°C/s and 100°C/s, respectively, the system may achieve fatigue loading rates of up to 1000 N/s. Specimens can be heated to temperatures of up to 1500°C with the help of the system's direct resistance heating system, and it can withstand reverse stress loading of up to 3000 N.

8800MT Controller & Controller Upgrades

Instron®'s newest controller for cyclic and static testing, the 8800MT, is optimized for fatigue testing. The 8800MT is the most recent in a long line of world-class controllers for testing materials. It is built to provide maximum security, dependability, and efficiency.

Stiffness Based Tuning is one of the functions available. This ground-breaking approach to calibrating fatigue testing systems enhances machine friendliness and contributes to higher data accuracy. It's easy for anyone to use, and you can get more consistent results without pre-cycling your specimen.

The controller is the brains of our ElectroPuls® test equipment and the latest hydraulic fatigue testing systems from Instron. The 8800MT's ability to communicate with any fatigue testing system, not just those made by Instron, is one of its most fascinating features.

Upgrading Systems with 8800MT
The 8800MT can be put on almost any hydraulic testing device for materials. Upgrading the controller on your current machines is a cost-effective way to give them a new lease on life and get the latest materials testing software.
