A new concept of sensor is proposed to measure friction at roll–strip interface during strip rolling. By measuring elastic strains inside the roll, it is possible to evaluate contact stresses at roll–strip interface using an inverse analysis, with the great advantage not to mark the strip with the sensor. Using simulations, this new sensor is designed and its ability to evaluate contact stresses is discussed as a function of rolling conditions: influences of roll thermal stresses, roll deflection, roll–strip contact length, distance of measurement points to roll surface on contact stress reconstruction by inverse analysis are characterised. Results show that this sensor could be used in various pilot hot and cold rolling conditions for friction evaluation. Next step of this work is a pilot rolling test of the sensor.
