Abstract
At the IFUM, a novel material inherent load sensor based on martensite transformation is under development. In metastable austenitic steels, mechanical load induces a partial transformation of austenite to martensite. The martensite content correlates with the magnitude of the load applied. The threshold of stress that initiates the phase transformation can be decreased locally by means of prior forming (e.g. stamping). This enables the detection of load below the yield stress by means of martensite content. A numerical material model to consider the load induced formation of martensite in the simulation is presented in this paper. Afterwards, an approach to detect the effective direction of load applied to the sensor is discussed.
