Type: Measure Hardware
Description: Fully-integrated dynamic and fatigue testing systems incorporate servo hydraulic, servo-electric and linear motor technologies. These test instruments cover a broad range of fatigue, dynamic, and static testing applications. Applications include high-cycle fatigue, low-cycle fatigue, thermo-mechanical fatigue, crack propagation and growth studies, fracture toughness, bi-axial, axial-torsional, multi-axial, high strain rate, quasi-static, creep, stress-relaxation, and other types of dynamic and static tests. Samples of materials or components undergo a range of tests in order to assess how a component will behave in various environments.

Units: Fatigue under various dynamic conditions.
Advantages: Will give a clear indication of life span of a component and how it will behave in extreme environments.
Limitations: Will cost a couple of prototypes which will be deliberately broken.
