Resonant Testing System for Dynamic Bending Applications

Cracktronic Resonant Fatigue Testing Machine - High Capacity Fatigue Tester

For Dynamic Bending Load Applications

Originally designed to precrack specimens for fracture mechanics, the current versions offer much more possibilities due to a modular concept:

• Bending up to 160 Nm
• Tension/Compression up to 8 kN
• Torsion

The kinematic conditions allow a pure bending moment between the gripping heads. An electromagnetic driven resonator, built as a rotary oscillator, creates an appropriate bending moment. Independent to the dynamic drive a static moment is possible to be applied to the specimen via a torsion rod.

Technical data:

• Available with 70 Nm and 160 Nm Loading
• Tension/ Compression up to 8kN
• Operating Frequency: up to 300 Hz
