Hydraulic Reverse-Stress Pullrods
Description
The 3117-501 pullrods reverse-stress pullrods with hydraulic preload designed for elevated temperature Low Cycle Fatigue applications. The pullrods are also suitable for hot tensile tests and other reverse axial stress applications.
Application Range
- Full reverse stress high temperature testing
- High temperature fatigue testing
- High temperature tensile testing
- High temperature fracture mechanics (when used with optional high temperature CT grips)
Features and Benefits
- Designed with an external rod diameter of 60mm to provide lateral stiffness for excellent alignment characteristics
- Provides proven repeatable alignment to Class 5 according to ISO12106 & ASTM E606 when used in conjunction with AlignPro alignment fixture 1
- Suitable for threaded or button headed specimens with the appropriate specimen adaptors
- Features replaceable specimen insert seats to enable easy refurbishment
- Lower pullrod includes integrated angular adjustment capability
- Interchangeable adapters allow various threaded-end and buttton specimen sizes to be accommodated
- Preloading mechanism is hydraulically driven - more repeatable than manually clamping
- “One touch operation” via the use of an electric pump (3117-503 only) thereby eliminating variations due to human error
- Scribed feature on pullrods to enable consistent rotational allignment
- Precision faces are all water cooled to allow tighter tolerances without the risk of seizing due to high temperatures
- No rotation of specimen or any components during clamping

LCF Brochure
Low Cycle Fatigue (LCF) testing is a growing area of materials testing, driven in particular by increasing demand from the aerospace, automotive and power generation industries. ISO 12016 and ASTM E606 specify the standard practice for strain controlled fatigue testing, used for simulating mechanical loading into the plastic region. This testing is typically carried out at very high temperatures to replicate the service conditions experienced by turbine blades in both gas turbines and jet engines.

8862 Servo-Electric Testing System
8862 systems have been the industry choice for Low Cycle Fatigue (LCF) testing for decades and are now fully integrated with our latest controller platform. Instron® has developed this system specifically to address the challenges of reverse-stress Low Cycle Fatigue and Thermomechanical Fatigue (TMF) testing. The unique actuator technology utilizes an all-electric, backlash free, ball-screw drive eliminating the need for hydraulic infrastructure to support the machine.

Furnace Controller & Software | 3117-301/302
Instron's revolutionary approach to furnace control solves one of the challenges of high temperature which is rarely discussed. Temperature control is notoriously challenging and dependent on expert technician's knowledge to configure, tune and optimise multiple temperature controllers to achieve the desired heating rate, set point and temperature gradients.
