Abstract

Pulse-Spectrum Technique (PST), a versatile numerical method capable of simultaneous determination of bulk and shear moduli and density variations in two-dimensional and three-dimensional test specimens with complex geometries, is developed for nondestructive evaluation. Numerical simulations are carried out to test the feasibility and to study the general characteristics of PST.
