In various situations, targets with different characteristic dimensions are being exposed to blast waves generated by high explosive detonation. One of the existing mitigation methods consists protecting target from explosion a sandwiched crushable core between front plate and target. The pressure is converted into planar displacement plate, which compresses core, delaying transmission load inf...

The friction in the swash plate type axial piston pumps is mainly influenced by fluid film interface. piston–cylinder interface one of key interfaces pumps. geometry determined gap between and cylinder. dimensions parts determine geometry, deformation structure also influences geometry. viscosity strongly temperature. Thus, a novel approach studying film, structure, temperature interaction prov...

We study the Landau-Levich problem, i.e., withdrawal of a plate from a bath of fluid, in the case of a soft-jammed system, which involves a transition from a solid bath to a solid layer stuck on the plate. We show that this solid-solid transition is prepared inside the bath before the emersion from the fluid, through the existence of a uniform (boundary) layer in the liquid regime along the pla...

An analytical model is developed for examining the vibro-acoustic properties of a fluid-loaded plate reinforced by periodic ribs of finite width. This model is used to understand the frequency filtering properties of the flexural wave and the structural-borne sound wave of the ribbed plate under different fluid loading conditions. The relationships between the flexural waves and the related sou...

The steady boundary layer flow and heat transfer of a viscous fluid on a moving flat plate in a parallel free stream with variable fluid properties are studied. Two special cases, namely, constant fluid properties and variable fluid viscosity, are considered. The transformed boundary layer equations are solved numerically by a finite-difference scheme known as Keller-box method. Numerical resul...

In this paper, we present a technique for the deposition of inks, toners, organic polymers, fuels, small solid particles, biological and chemical fluids, using a fluid ejector. The ejector design is based on a flextensional transducer that excites the axisymmetric resonant modes of a clamped circular plate. It is constructed by depositing a thin piezoelectric annular plate onto a thin, edge cla...

In this study, effects of numerous physical quantities like dissipation, thermal radiation, and induced magnetic field on magnetohydrodynamic Casson fluid flow through a vertical plate is addressed. The non-dimensional multivariable governing equations are solved numerically by by means of Runge-Kutta method along with shooting technique. The behavior of velocity, temperature and induced magnet...

Deformable components such as sandwich structures possess promising properties for use in protection systems. Detailed studies on energy absorption and fluid–structure interaction effects are necessary the application of deformable blast resistant design. In this paper, an existing shock tube facility has been extended with a transparent section to observe measure fluid flow structural response...

Geometric and material nonlinear behavior of slender webs in I-column girders having stocky flanges under the action of combined lateral and axial loads is investigated. Interaction curves corresponding to the application of compressive and shear loads at buckling and ultimate stages for both web plates and column sections are plotted. In addition, the effects of flange and web slenderness rati...
