Acoustic bulletin, Vol. 2 3, (1999) p.33-41
There is considered an axisymmetrical problem on harmonic vibration of poroelasticity liquid-filled layer located a rigid base disturbed by impermeable piston-type load. Using Hankel's integral transform the analytical solution of corresponding boundary-value problem for system equations of M. Biot is found. As a result of numerical modelling, the characteristics of pressure and stress fields in layer were obtained, and energetic peculiarities of vibration in dependence of frequency are analyzed.
