Forced ice-shelf oscillations modeling was undertaken employing a full 3D finite-difference model of an elastic ice shelf that coupled to treatment under-shelf seawater flux. The flux described by the wave equation, which includes pressure excitements in shallow water layer under shelf. Thus, flexure produced hydrostatic below-shelf seawater. Numerical calculations were performed for idealized ...

Thin plate splines have been used successfully to model curves and surfaces. A new application is in data mining where they are used to model interaction terms. These interaction splines break the \curse of di-mensionality" by reducing the high-dimensional nonparametric regression problem to the determination of a set of interdependent surfaces. However , the determination of the corresponding ...

This study proposes an elastic compact Piezoelectric energy harvester (PEH) in multiple configurations, including a single cantilever beam, beam with hole, two beams hole contributing towards wider operating bandwidth. The are designed structural forms and section shapes, symmetrical uniform rectangle frames. Natural frequencies, vibration modes, output voltages of PEH estimated using Finite el...

Measurement of stress-strain curves under tension-compression reverse loadings is crucially important for the understanding Bauschinger effect aluminum alloy sheets. Uniaxial compression sheet metals carried out with supporting flat plates, which clamp a specimen to prevent it from buckling. The forces generate thickness stress and friction forces. In present study, influence force on curve val...

The effects of splitter plate as a passive turbulence control on the transverse vibration characteristics cantilevered rectangular prism with different finite length (aspect ratio L/H) and depth ratios (side D/H 0.2 0.5) was investigated in water tunnel. A installed behind small gap sufficient to prevent vortex shedding intrusion. It enhances response amplitude ascended linearly respect non-dim...

A closed-form analytical solution procedure is proposed to solve the coupled fluid-structure interaction (FSI) equations that involve first-order Doubly Asymptotic Approximation (DAA1) formulation. An efficient method comprised of nonstandard finite difference (NSFD) scheme applied. First all, are developed analyze response a rigid mass-spring oscillator in an air-backed condition when it subje...
