Project description

In laboratory conditions, the fatigue behaviour of materials is typically characterized by applying cyclic loads to the material. For certain material types and/or specimen geometries, the load amplitudes in fatigue are very small. Classical servohydraulic machines are not able to accurately apply these small load amplitudes. A linear electric actuator can control those very small loads precisely in fatigue.
