Finite element analysis of geodesically stiffened cylindrical composite shells using a layerwise theory
Layerwise finite element analyses of geodesically stiffened cylindrical shells are presented In this work. The layerwise laminate theory of Reddy (LWTR) is developed and adapted to circular cylindrical shells. The Ritz variational method is used to develop an analytical approach for studying the …

Optimal design of geodesically stiffened composite cylindrical shells
… to obtain minimum-weight designs of composite stiffened structures. Ply thicknesses, ply orientations, and stiffener heights can be used as design variables. Buckling, displacement, and material failure constraints can be imposed on the design. The system is used to conduct a design study of …

Stress and buckling analysis of grain silos under snow or wind loads
… devise a simple yet reliable method of analyzing stiffened shells of revolution. As an example a grain silo with a conical roof is studied under the action of snow or wind load. First the silo is analyzed by the current simplified conventional method. Simplifications include ignoring the presence …

Feasibility of helically stiffened construction for a formula racing car structural shell
… widely used sandwich construction with helically stiffened construction for a Formula racing car structural shell is studied. The torsional deformation behavior of circular and square cross-section shells is analyzed as an approximation to the real car structure. Shells with different sandwich and …

Buckling Analysis of Composite Stiffened Panels and Shells in Aerospace Structure
Stiffeners attached to composite panels and shells may significantly increase the overall buckling load of the resultant stiffened structure. Initially, an extensive literature review was conducted over the past ten years of published work wherein research was conducted on grid stiffened composite …

Automation and Expert System Framework for Coupled Shell-Solid Finite Element Modeling of Complex Structures
… multi-fidelity models of a highly complex stiffened thin-walled pressure vessel under external and internal tank pressure is presented. Results reveal that automation of multi-fidelity model generation in an integrated fashion including the geometry creation, meshing and post-processing can …
