Pressure measurement sensor for jointed structures

Abstract

The talk will deal with measurements of normal loads in assembled structures. A new sensor has been developed to measure the distribution of the normal force in a bolted joint. This sensor is piezoelectric and is associated to an electronic device for carrying out a static measurement. Moreover, the electrode of the sensor is shaped in order to make possible the measurement of a detailed normal stress field. Furthermore, preliminary results of the study of the vibrations are presented. © The Society for Experimental Mechanics, Inc. 2013.
