Dynamic Characteristics of Structures Extracted from In-situ Testing
Hal Amick, Michael Gendreau, and Ahmad Bayat
The paper discusses two primary areas of interest in a structural evaluation. First, in-situ measurements are used to confirm the predicted structural stiffnesses and resonance frequencies. Second, the evaluation characterizes the manner in which vibrations are propagated through the structure. Methodologies are presented for carrying out these measurements, and typical data are given.
