Résumé

The aim of this study is to evaluate the sensitivity of Nonlinear Resonance Ultrasound Spectroscopy (NRUS) to torque changes, in a system composed of a screw tightened in a block of different materials. These materials have been chosen to exhibit very different elastic and dissipative properties. The system is excited under its first compressional mode. Nonlinear parameters expressing the importance of resonance frequency and damping variations are extracted. Then, linear and nonlinear parameters are compared and their sensitivity is discussed for each material. Results suggest that an NRUS measurement can be an appropriate and sensitive method for monitoring of bolt tightening, complementary to linear methods. Further work will have to be carried out to apply this method in medical or industrial contexts.
