Product catalog summary
Overview
The Instron® 8801 is a compact servohydraulic fatigue testing system designed for both static and dynamic testing of materials and components. It is particularly suited for fatigue testing and fracture mechanics, offering a complete solution for advanced testing needs.

Features
  • Double-acting servohydraulic actuator with a force capacity of up to ±100 kN (±22 kip).
  • High-stiffness, precision-aligned load frame with twin columns and actuator in the lower base.
  • 150 mm (6 in) usable stroke, suitable for dynamic and static testing.
  • Compact design requiring less than 0.5 m² (5.4 ft²) of floor space.
  • Patented Dynacell™ advanced load cell technology for faster testing and reduced inertial errors.
  • Compatible with a wide range of grips, fixtures, chambers, and other accessories.

Controller and Software
The system includes a digital 8800 controller for full system control, featuring automatic loop tuning, amplitude control, and adaptive control technology. It supports WaveMatrix™ Dynamic Testing Software and Bluehill® Software for static tests.

Typical Testing Applications
  • High-Cycle Fatigue: Utilizes mechanical or hydraulic grips and dynamic extensometers for high-frequency fatigue testing.
  • Fracture Mechanics: Configurable with CT grips or flexure fixtures for crack growth and fracture toughness studies.
  • Thermomechanical Fatigue (TMF): Simulates mechanical fatigue with thermal cycling using specialist heating technologies.
  • High-Temperature Testing: Conducts low-cycle fatigue and other tests at very high temperatures.
  • Composite Testing: Essential for understanding the cyclic properties of composite materials in critical applications.
  • Environmental Testing: Uses chambers to study material properties at various temperatures.

Specifications
  • Dynamic Load Capacity: ±50 to ±100 kN (±11 to ±22 kip).
  • Actuator Stroke: 150 mm (5.9 in).
  • Frame Stiffness: 390 kN/mm.
  • Operating Environment: +10 to +38°C (+50 to +100°F) with 10 to 90% humidity non-condensing.
  • Hydraulic Pressure Supply: 207 bar (3000 psi).
  • Electrical Supply: Single-phase mains 90-132 or 180-264 VAC 45/65 Hz.
