Tg. Geers et Pz. Zhang, DOUBLY ASYMPTOTIC APPROXIMATIONS FOR SUBMERGED STRUCTURES WITH INTERNAL FLUID VOLUMES - EVALUATION, Journal of applied mechanics, 61(4), 1994, pp. 900-906
The accuracy of the doubly asymptotic approximations formulated in the
previous companion paper is examined through the comparison of DAA an
d exact transient response histories for a fluid-filled, submerged sph
erical shell excited by an incident plane step-wave, The numerical res
ults indicate that second-order DAAs are satisfactory for problems of
this type.
