Abstract

In the literature, there are several examples where wires of magnetostrictive material are used for both sensing and nondestructive inspection applications. However, the magnetostrictive material may not be suitable for certain environments (such as corrosive environments). Therefore, designs where the magnetostrictive material is coupled to a more robust waveguide material are of interest. The work presented in this paper examines a design based on a cylindrical sleeve of magnetostrictive material. Experiments were conducted to compare the new sleeve design to the old approach of using a brass coupling. In addition to simplifying the manufacturing process, the sleeve design was found to eliminate signal artifacts encountered in previous results.
