A.M.Gomilko, A.N.Trofimchuk An asymptotic solution of a harmonic contact problem for an impermeable piston on a porous-elastic bed |
Acoustic bulletin, Vol. 1 ¹ 3, (1998) |
| The paper deals with obtaining and analyzing of the asymptotic solution of the harmonic contact problem on vibration of a rigid impermeable piston situated on fluid-saturated porous-elastic half-space. When frequency approaches zero, the effective contact stress has been sown to have the root singularity in the vicinity of the stamp's edge. The contact pore pressure is a smooth function, the decrease rate of which amplitude depends on involving/neglecting of viscosity of the fluid filling the porous medium. |
