In this paper, an attempt is made for solution of free vibration analysis of annular plate reinforced with carbon nanotubes for Uniformly Distribution (UD), resting on an elastic foundation using a refined theory presented. In this theory, a parabolic distribution of shear stress and strain in the thickness direction and satisfies the boundary conditions of zero shear stress on the upper and lo...

In the present work, thermo-electro vibration of the piezoelectric nanoplates resting on the elastic foundations using nonlocal elasticity theory are considered. In-plane and transverse displacements of the nanoplate have been approximated by six different modified shear deformation plate theories considering transverse shear deformation effects and rotary inertia. Moreover, two new distributio...

The effect on raft foundation of a barrage due to varying stratum has been examined using finite element analysis. The raft foundation is completely resting on soil media and surrounded by soil and rock media. Eight noded brick elements have been used for three-dimensional modeling and meshing of the rock, soil, cut-off, pier, beam and abutment but raft foundation has been meshed using plate el...

The response of back-supported buffer plates comprising a solid face sheet and foam core backing impacted by a column of high velocity particles (sand slug) is investigated via a lumped parameter model and coupled discrete/continuum simulations. The buffer plate is either resting on (unattached) or attached to a rigid stationary foundation. The lumped parameter model is used to construct maps o...

From the differential equation of the doubly curved shell in terms of the displacement components u, v and w it is apparent that, in so far as the flexural phenomena are concerned, the shell can be considered as a flat plate on an elastic foundation, at a~y rate in a region of sufficiently small size to be regarded as quasi-Euclidean around the vertex of the osculating paraboloid. The modulus o...

In this paper, the experimental vibration analysis of a single cylinder air compressor based on a hypocycloid straight line mechanism (HSM) is investigated. The HSM mechanism uses planetary gears to convert rotational motion to purely linear motion. In the conventional air compressor, the slider- crank mechanism is replaced by the HSM mechanism with appropriate counterweights. The constructed s...
