    Abstract

    Nondestructive evaluation techniques have been used to evaluate the integrity of bolted joints in structures. One such method is nonlinear wave modulation spectroscopy (NWMS), which examines the sideband generation in the presence of dual inputs as a result of nonlinearity present in the system. This work uses NWMS on an aluminum T-joint structure to evaluate the torque levels of the bolts. In addition, this work compares excitation with two shakers to excitation with a single shaker and an impact hammer, in which the hammer excites several low frequency modes. The results show that the damage indicator based on the sidebands is highly dependent on damage and sensor location, and that the damage indicator is most sensitive over a specific range of torque levels.
