Doubly asymptotic approximations for vibration analysis of submerged structures
TL;DR: Geers and Underwood as discussed by the authors examined the use of first and second order DAA's for vibration analysis of submerged structures and found that the first-order DAA is inadequate and the second-order forms show considerable promise.
