Stiffened Sheathings of Orthotropic Cylindrical Shells [PDF]
Journal 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 ...

IDENTIFICATION OF ELASTIC PROPERTIES OF STIFFENED COMPOSITE SHELL [PDF]
Aviation, 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
Periodica 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.
