This article introduces a single cylinder fatigue machine adaptable to a scanning electron microscope chamber. The machine includes a node control mechanism to create a still observation node at any location on the specimen as fatigue cycling occurs, thereby allowing a point of interest to remain within view. The exceptional stability of this machine enables improved in situ study of the fatigue cracking phenomenon. For example, an in situ machine enhances the researcher’s ability to record material structural changes that precede crack nucleation and allows observation of the influences of microstructure (grain structure) on the early stages of crack propagation.
