Abstract
Within the framework of the Collaborative Research Center (CRC) 653 "Gentelligent Components in Their Lifecycle" a study on a novel material inherent load sensor based on phase transformation is carried out. In metastable austenitic steels, mechanical load induces a partial transformation of austenite in martensite. The martensite fraction correlates to the magnitude of the load applied to the material. The threshold of stress to initiate the phase transformations can be decreased locally by means of prior forming. A subsequent change of the martensite fraction within the stamped areas can be determined and gives information concerning the load history. The important advantage of this approach is the decrease of the stress threshold which is necessary to initiate the formation of martensite. With this property, the stresses below yield stress can be detected by means of martensite fraction. Therefore a mathematical model to consider the load induced formation of martensite in FE simulation was developed. With the help of this model, the development of the load sensor is assisted. Other main topics of this paper include an approach to detect the magnitude of the load with the help of the sensor technology and the experimental research.
