Detection of a cavity in a rod using the negative mass method
Source abstract
Abstract
A negative mass method is proposed, by which new results on the location and dimensions of a defect in the form of a small cavity in a rod are obtained from the natural frequencies of its bending vibrations. The application of this method does not depend on the form of the cavity. The volume of the cavity is modeled by the absolute value of the negative lumped mass of the rod.
