A case study is presented in which the first steps are made towards development of a structural health monitoring (SHM) data fusion framework. For this purpose, composite single-stiffener panel subjected to compression-compression fatigue loading (R = 10). The carbon-epoxy contains an artificial disbond 30 mm, was created using Teflon insert during manufacturing and placed between skin stiffene...

this article considers the seismic behavior of beam-to-column joints in steel frames for different bolt arrangements by using of finite element modeling. as the most important beam-to-column joint type, the beam-to-column joints with end-plate is chosen for the analysis. four different specimens have been analyzed. these models had some differences such as bolt arrangement and the presence or a...

~This report presents the first stage of an investigation of the response to random noise of a stiffened cylinder, representing an aircraft fuselage, including an analysis of the lower modes of such a cylinder. Preliminary investigations suggested that assumptions and approximations which are valid for the uniform, i.e., unstiffened, shell are not necessarily valid for a shell with heavy stiffe...

Presented is a study of the tripping strength of asymmetrical longitudinal plate stiffeners subjected to a combination of axial and lateral loads. The loaded edges were taken to be simply supported. The method of analysis is based on the principle of minimum total potential, and ten displacement functions were used to describe the deformations of the plate and stiffeners. First yielding was use...

A new method has been proposed in this study for the elastic-plastic buckling analysis of stiffened panels under global bending. In method, a simplified model built with application two theories plasticity, incremental theory (IT) and deformation (DT). The effect transverse shear through stiffener thickness considered using Mindlin-Reissner plate theory. governing differential equations have so...
