The effect of a distributed patch mass on the natural frequency of vibration of a laminated rectangular plate with simply supported boundaries is investigated. The third order displacement field of a composite laminated rectangular plate is defined using the two variable refined plate theory. Equations of motion of the plate are obtained with the help of calculus of variation. Parametric study ...

Complex analysis of characteristic of underwater noise allows to find several features typical for underwater noise produced by ships as well as correlations between mechanical activity of ship’s mechanism and generated underwater sound. Their vibration activity might be reduced by applying active treatments utilising piezoelectric sensors and actuators. The paper explores the potentials of act...

Composite materials are used in aeronautical, automobile, healthcare and marine industries due to their high stiffness, higher strength-to-weight ratio long fatigue life. Thin plate plays vital role manufacturing of engineering structures. Components made from composite often subjected damage while working. Buckling can cause loss stability component which subsequently leads failure the entire ...

Abstract In this paper, we conduct research of the waveguide strength under icing. Icing is assumed to be uniform along perimeter and length waveguide, so ice deposits considered in form an equivalent increase density structure. As a result, icing problem reduced gravitational bending waveguide. Waveguide has thin-walled rectangular cross-section; therefore, solution demand using theory plate. ...
