Nondestructive holographic interferometry methods for the dynamic structural analysis of a graphite-epoxy folymer composite structure

摘要

Holographic Interferometry has been successfully employed to characterize the materials and behavior of diverse types of structures under stress~(1,2,3). Such applications of holographic The technology is nondestructive, real-time, and definitive in allowing the identification of vibrational modes, displacements, and motion geometry. Structures and processed materials can be analyzed with very low amplitude excitation and the resultant data can be used to adjust the accuracy of mathematically derived structural models.
