✦ Synopsis
The dispersion of the axisymmetric stress waves propagated in the in"nite hollow cylinder "lled with water is studied. Modi"cation of a semianalytical FE approach for &&dry'' cylinders for this case and other independent FE approaches are described. The usage of the approaches in question is demonstrated for thick and thin cylinders in cases of isotropic and composite (monoclinic) materials. In#uence of water upon the dispersion properties of waves is demonstrated by dispersion curves and shapes of waves. Some dispersion curves were in#uenced by #uid only weakly, but some dispersion curves were in#uenced very strongly even for very thick cylinders. 2001 Academic Press *u/*x w/r *w/*r *v/*r!v/r *w/*x#*u/*r *v/*x e g g g f g g g h
