... amplitude motion. The viscous and compressible fluid forces, formulated in terms of convolution products, are linked to fluid history effects induced by wave propagation phenomena in the fluid domain. These models are expressed with dimensionless parameters and illustrated for a specific motion imposed...

...Fei Deng; Bin Wu; Cunfu He The temporal-spatial focusing effect of the time-reversal method on the guided wave inspection in pipes was investigated theoretically in the current research with a transfer function. The amplitude of the time-reversed wave propagating along the pipes was not only...

...-structure interaction and damping effects were taken into consideration. An analytical solution for the displacement, stress, and pressure wave propagation in the fluid-tube system was obtained. The developed model predicted localized critical regions where the structure might experience failure. Since...

...Denis D. Rickman; Donald W. Murrell The interaction of an airblast wave with a structure, and the blast wave propagation around and over the structure is of significant importance. In order to protect a structure from the airblast produced by such explosive threats as terrorist bombs, a facility...

...A. C. Seibi; A. Karrech; T. Pervez This paper presents a mathematical model of post-expansion tube response under mechanical expansion. The stress, pressure, and displacement waves propagating through the tube-fluid system and their effect on the tube response are studied. The model takes...
