Cylindrical Panel Like Response of Fully Surface Parallel Restrained Simply Supported Hyperbolic Paraboloidal Thick General Cross-ply Panels

Free vibration Study of simply supported cylindrical laminateds panels with piezoelectric layer

In the present study, vibration of cylindrical laminates with different layers and angles were studied. In order to actuate and polarize in radial direction, a piezoelectric layer was located at outer surface of composite shell. Laminates were assumed long enough so that plane strain state analysis in 2D can be used properly. In order to satisfy the boundary conditions, variables in terms of Fo...

Free Vibration of Hexagonal Panels Simply Supported at Discrete Points

A Simply Connected Surface of General Type

In this paper we construct a simply connected, minimal, complex surface of general type with pg = 0 and K 2 = 2 using a Q-Gorenstein smoothing theory and a rational blow-down surgery.

Active control of simply supported cylindrical shells using the weighted sum of spatial gradients control metric.

It is often desired to reduce sound radiated from cylindrical shells. Active structural acoustic control (ASAC) provides a means of controlling the structural vibration in a manner to efficiently reduce the radiated sound. Previous work has often required a large number of error sensors to reduce the radiated sound power, and the control performance has been sensitive to the location of error s...
