Optimum Design of Curvilinear Stiffened Panels with Stiffening Beams

Applied Mechanics and Materials, 2013
The paper presents a framework for design and optimization of curvilinear stiffened panels with any cross-section shape of stiffener. Within this framework, the weight of stiffened panel applied complex loads, is minimized under the constraints of structural responses include global buckling, maximum stress and crippling.

Stiffened panels with varying stiffener sizes

The Aeronautical Journal, 1973
Stiffened panels usually consist of a skin of uniform thickness with several identical equally spaced longitudinal stiffeners. This paper demonstrates that the weight of a panel which is designed to have a specified initial buckling load, in uniform longitudinal compression, can be reduced by using more than one size of stiffener.Initial buckling ...

Response of stiffened sandwich panels

22nd Structures, Structural Dynamics and Materials Conference, 1981
An increasingly important part of the design of skin-stringer systems, such as those found in flight vehicles, is the ability to reduce surface vibration levels when they are subjected to the dynamic loads of jet, or propeller noise. One common method of reducing the response of these structures is by layered construction using viscoelastic materials ...

Buckling and Failure of Flat Stiffened Panels

Journal of Aircraft, 1974
Compression panels, regardless of the local buckling of the skin, can be divided into three regions: short panels, having slenderness ratio equal to or less than 10, long panels, which are shown to fail essentially because of the long wave buckling of the skin, and panels of intermediate length in the transition region.

Measurement of Stiffener Stresses and Effective Widths in Stiffened Panels

Journal of the Aeronautical Sciences, 1939
In the design of a stressed skin metal airplane it is essential that correct stiffener stresses and effective widths of skin acting with the stiffener be known in order to insure tha t fictitious margins of safety in wing and fuselage analyses are not shown.

Predicting Stiffener and Stiffened Panel Crippling Stresses

Journal of the Aeronautical Sciences, 1942
An empirical method is presented for predicting the crippling stress at L/p < 20 of 24S-T Alclad bent-up sheet stiffeners, 24S-RT Alclad bent-up sheet stiffeners, and 24S-T extruded stiffeners acting alone or in conjunction with 24S-T Alclad sheet as a panel.

Optimiation of the flat stiffened panels

Proceedings. The 8th Russian-Korean International Symposium on Science and Technology, 2004. KORUS 2004., 2005
The safety of operation of designs is now an actual problem. With this purpose at the initial stage of designing it is necessary to provide a significant amount of requirements, frequently inconsistent. For example, it is restrictions on strength, stability, resource of elements of structures, constructive-technological restrictions etc. For many types

Buckling of Stiffened Panels

2013
This chapter presents the basic configurations of stiffened panels commonly used in ship construction. A comprehensive analysis of buckling of stiffened panels is introduced. Global and local buckling modes of deformation of stiffened panels are given. The commonly used idealizations of boundary support conditions of ship plating are clarified.

Welding Effects on Thin Stiffened Panels

2007
The major problems due to welding effects are the residual stresses and deformations of which the levels affect more or less the resistance and lifetime of welded structure.

Effect of sequence and stiffener shape on welding distortion of stiffened panel

Journal of Constructional Steel Research, 2018
Abstract Welding is extensively used in industries for the assembly of different products including ships, automobiles, trains, bridges etc. Welding distortion is usually a source of dimensional imprecision in assembly and higher manufacturing costs.
