8801 Servohydraulic Fatigue Testing System - 3

High-Temperature Testing Environmental Testing Low-cycle fatigue (LCF) and other tests can be carried out at very high temperatures using furnace technologies and specialized load strings. Environmental chambers provide the capability to study mechanical properties of materials and components at high or low temperatures. Composite Testing Fatigue testing is critical for understanding the long-term cyclic properties of composite materials - especially for mission critical applications such as aerospace, wind turbine, and automotive applications. Thermomechanical Fatigue (TMF) Using...
