Zusammenfassung:This paper introduces a modified control cir-cuit of static tensile stage of Cambridge S-200SEM.The function of the stage is extended to thatof a tensile/compressive dynamic fatigue testingstage.It can be used for studying fatigue microcharacteristic and crack growth.Direct observa-tions of small crack growth behaviour were carriedout under the SEM with modified stage.Resultsshowed the various stages in the development of acrack.
