In this paper, the effect of anisotropy on the free vibration of laminated rectangular plate supporting a localized patch mass is investigated. The two variable refined plate theory is applied to define the third order displacement field of a composite rectangular plate. The plate is considered to have simply supported boundaries. The equations of motion for rectangular plate are obtained by ca...

Abstract In this work, we study the transversal vibration of thin periodic elastic plates through asymptotic homogenization. particular, consider soft inclusions and rigid with coatings embedded in a stiff matrix. The method provides general expression for dynamic surface density plate, which compute analytically circular or numerically two-way ribbed plates. Through homogenization, find that b...

This study examined the flexural behavior of poplar laminated veneer lumber (LVL) box floor with orthogonal rib beams. Four 3.6 m × 4.8 samples made LVL beams and oriented strand board (OSB) plates were tested under vertical uniform loading, from which bearing capacity, stiffness, failure characteristics analyzed. There was no damage in all at normal service load 2.5 kN/m2, maximum deflection f...

An analytical and numerical solution for the free vibration of laminated polymeric composite plates with different layups is studied in this paper. The governing equations of the laminated composite plates are derived from the classical laminated plate theory (CLPT) and the first-order shear deformation plate theory (FSDT). General layups are evaluated by the assumption of cross-ply and angle-p...

The strain of an optical fiber, embedded in a composite laminated plate, was measured using radio frequency iiiterferometery. While the response of a similar fiber glued to the plate was linear with the applied loading, the strain experienced by the embedded fiber exhibited significant fluctuations around the linear expected trend. This phenomenon is qualitatively described in terms ofpolarizat...

An asymptotic method based plate analysis is carried out for composite laminates including interfacial imperfections. By scaling of the thickness coordinate with respect to the characteristic length of the plate, the initial three-dimensional governing equations are separated into the microscopic through-the-thickness equations and macroscopic plate equations. In the microscopic 1D analysis, fi...
