Fatigue test systems are specialized testing setups used to measure the endurance performance of materials and engineering components under repeated loads. These systems work to determine when and how a part will fail under long-term dynamic stress. Fatigue tests enable the prediction of design life by establishing the material’s S-N curve (stress-life relationship).

Fatigue test systems typically apply repeated force/moment to specimens using hydraulic, electromechanical or servo motor-driven actuators. During testing, parameters such as the material’s stress, strain, cycle count and crack formation process are recorded. The system operates according to predetermined load profiles (sine waves, random vibration, block loading, etc.) to simulate real working conditions.

At E2T, we develop customized fatigue test systems that can simulate environmental conditions according to our customers’ needs. With the E2T Control Suite, we provide turnkey solutions for your fatigue testing needs by performing real-time control and data acquisition with high precision and at high frequencies.
