Stiffened Sheathings of Orthotropic Cylindrical Shells [PDF]

open access: yesJournal of Structural Engineering, 1992
Geometric characteristics of orthotropic shells introduce computational difficulties (discretization of the stiffeners, computing time, interaction at the ring and stringer junctions with the sheathing, etc.). Navigation-dam gates, tidal surge barriers, etc., are hydraulic steel structures composed of orthotropic sheathings, which can now be more ...

An analytical approach to analyze nonlinear dynamic response of eccentrically stiffened functionally graded circular cylindrical shells subjected to time dependent axial compression and external pressure. Part 2: Numerical results and discussion

open access: yesVietnam Journal of Mechanics, 2014
Based on the classical thin shell theory with the geometrical nonlinearity in von Karman-Donnell sense, the smeared stiffener technique, Galerkin method and an approximate three-term solution of deflection taking into account the nonlinear buckling ...

IDENTIFICATION OF ELASTIC PROPERTIES OF STIFFENED COMPOSITE SHELL [PDF]

open access: yesAviation, 2009
In the present study a numerical-experimental method for the identification of the elastic properties of stiffened composite panel from experimental vibration analysis is carried out. The elastic properties of a panel are found by an identification procedure based on the method of experiment design, the response surface approach, and the finite element

Symmetric Stiffened Shell Structures

open access: yesPeriodica Polytechnica Transportation Engineering, 2015
In this paper the analysis of the symmetric stiffened shell structure are introduced. The main purpose of this paper is to reduce the number of the unknowns in the compatibility equation to ease vehicle preliminary design process. One shell field contains a square-shaped shell and four rod with joints in the corner.

Relative performance of antisymmetric angle-ply laminated stiffened hypar shell roofs with cutout in terms of static behavior

open access: yesCurved and Layered Structures, 2016
A review of literature reveals that bending analysis of laminated composite stiffened hypar shells with cutout have not received due attention. Being a doubly ruled surface, a skewed hypar shell fulfils aesthetic as well as ease of casting requirements ...
