Project Title

STUDY OF SURFACE AND LAMB TYPE WAVE PROPAGATION IN THE CONTEXT OF SIZE DEPENDENT PIEZOELECTRICITY

Summary

Piezoelectric actuators and sensors have been widely used in damage detection of various structures including beams, plates and pipes due to their unique sensing and actuating properties. Researchers have also shown that closed-form solutions accounting for the electro-mechanical coupling of piezoelectric plates, laminates or patches are difficult to obtain especially for complicated boundary conditions. In this project analytical expression for the dispersion equation guiding the surface waves and Lamb will be obtained and the effects of various parameters like internal length scale parameter, dielectric strength on the phase velocity will be examined. Obtained results will be useful for the persons/industries involved in the similar kind of experimental studies.
