In this dissertation, a viscoelastic particulate composite (VEPC) is proposed for the improved constrained layer damping (CLD) treatment of structural vibration/dynamic instability. This VEPC is comprised of micro-sized ...

End forming of tubes generally refer to making of simple or complex shapes such as expansions, reductions, flares, flanges, tapers, and beads made at the end of the tube by single or multiple metal forming operations. These ...

This dissertation deals with the active control of flexural vibration of annular plates through the design of two new piezoelectric fiber composite (PFC) actuators in the cylindrical coordinates. The first one is an extension ...

Recent instabilities in the world energy market due to depletion of fossil fuel source, global worming threat and increasing price of fossil derivatives necessitate the need of harnessing the clean and renewable sources of energy.

In this work, a new varying order based NURBS discretization is proposed to enhance the performance of isogeometric analysis (IGA) technique within the framework of computational contact mechanics. The proposed method ...

The dynamics of free surface flows have been of great interest to researchers for centuries because of its applications in a variety of industrial processes and due to the richness of the underlying physics. The present ...

Electromagnetic forming (EMF) is a high strain rate forming process that utilizes high strength electromagnetic pressure to form tubes and sheets in the desired shape. High strain rate forming process successfully addresses ...

Magnesium alloys have low density, high specific strength, high stiffness, superior damping capacity, high thermal conductivity and good electromagnetic shielding characteristics. These properties make them suitable for a ...

In the present study, bio-ceramic material like biphasic calcium phosphate (BCP), hybrid BCP-TiO2 were deposited on the surface of bare as well as textured Ti-6Al-4V substrates using RF magnetron sputtering. BCP films were ...

Surface texturing is a new emerging area of research in the field of hydrodynamic lubrication...
