Free Vibration of Stiffened Plate with Cracked Stiffeners

Advances in Applied Mathematics and Mechanics
Summary: In this paper, a new cracked stiffener model for the stiffener with a part-through and open crack is proposed, considering the compatibility condition of displacements between the plate and the stiffener. Based on the first-order shear deformation theory, the free vibration of stiffened isotropic plates with cracked stiffeners are investigated

Stiffened plates with arbitrarily oblique stiffeners

International Journal of Solids and Structures, 1990
Abstract An analysis for a stiffened plate with arbitrarily oblique and equally spaced eccentric stiffeners is proposed. In this analysis, the joint effects of stiffeners by the interaction of the plate and stiffeners are taken into account and the effects of stiffeners are not considered as discrete members, but their effects are averaged or ...

Parametric Resonance of Stiffened Rectangular Plates

Journal of Applied Mechanics, 1972
This investigation is concerned with the onset of parametric instability of a simply supported stiffened rectangular plate subjected to in-plane sinusoidal dynamic forces. An analytical analysis is developed for the stiffened plate with the stiffeners treated as discrete elements.

Stiffened plates in bending

Computers & Structures, 1994
Abstract A semianalytical method developed by the author for the analysis of bare plates has been extended to the static analysis of stiffened plates. Both concentric and eccentric stiffeners have been considered. Deposition of the stiffener eccentric to the plate gives rise to axial and bending displacements in the middle plane of the plate.

A Stiffened Plate Element Model for Advanced Grid Stiffened Composite Plates/Shells

Journal of Composite Materials, 2010
A triangular composite stiffened plate/shell element is developed to analyze the advanced grid stiffened (AGS) structures based on Mindlin shear deformation theory. The rotations of ribs and skin are interpolated, respectively, while the conditions of displacement compatibility are satisfied along the interface of rib and skin.

The problem of the equilibrium of a plate reinforced with stiffeners

Journal of Applied Mathematics and Mechanics, 1999
The authors consider the equilibrium of a loaded plate with rigid ribs. The existence of a generalized solution to the problem is proved, and nonuniqueness of solution to the nonlinear problem under consideration is discussed.

On the elastodynamics of stiffened plates

Ingenieur-Archiv, 1990
A method of determining the response of a stiffened elastic plate to a dynamic excitation is presented here. Green's function for such a combined system has been systematically derived based on the eigenfunctions of the system obtained through the application of Galerkin's method. With that Green's function a wide range of dynamic forcing functions can

A New Stiffened Plate Element for the Analysis of Arbitrary Plates

Thin-Walled Structures, 2001
In spite of the large number of finite elements developed so far, most of these lack in generality, and are found to be inadequate and inefficient in some way or other, when it comes to analyzing plates of arbitrary geometrical configurations. So far the isoparametric element has been the most successful among available elements because of its ability ...

Demand on Stiffeners in Stiffened Extended End-Plate Connections

Advances in Structural Engineering, 2012
The paper reports a study on the effect of stiffeners on stiffness and strength of T-stubs to find out the strength and stiffness demand on stiffeners. The tensile capacity of triangular stiffeners is first analyzed and is compared with that of a long rectangular one, an efficiency factor formula is proposed. A triangular stiffener with length-to-width

Orthotropic Plate Model of Hat Stiffened Plate

Proceedings of the Institution of Mechanical Engineers, Part M: Journal of Engineering for the Maritime Environment, 2013
Orthotropic Plate Model of Hat Stiffened Plate has been developed based on the equal rigidity concept that makes use of orthotropy rescaling technique. This Orthotropic Plate Model can readily be analyzed using an orthotropic plate finite element available in the element library of any general-purpose finite element software, which will reduce the ...
