We manufactured sandwich-walled cylindrical shells with aluminum pyramidal truss core of constant curvature employing an interlocking fabrication technique for the metallic core. The skins were made of carbon-fiber reinforced composites and co-cured with the metallic truss core. Thereafter, we carried out axial compression tests on some representative samples to investigate the failure modes of...

Recent studies have shown that social networks exhibit interesting characteristics such as community structures, i.e., vertexes can be clustered into communities are densely connected together and loosely to other vertices. In order identify communities, several definitions were proposed characterize the density of connections among vertices in networks. Dense triangle cores, also known k-truss...

This paper investigates the inertial force effect on nonlinear aeroelasticity of flexible wing aircraft. The geometric are nonlinearity due to rotational and tension stiffening. The effect of large bending deflection will also be investigated. Aeroelastic analysis will be conducted for a truss-braced wing aircraft concept with nonlinear effect of large bending deflection and inertial force coup...

Strut and tie models consist of axial force members which react on one another and on external supports through nodes, i.e. they are trusses. An analysis of a truss problem is normally entered by reducing it to a line diagram of member centrelines representing the lines along which the stress resultants in the members are intended to act. When forces are concentrated in a line diagram the nodes...

Truss structures are widely used in construction of large-scale buildings. Design of steel structures is standardised in detail through set of European standards called EUROCODE. One of these standards, ENV 1993-1-8 deals with design of joints, but it does not cover the design of conical element for reduction of circular hollow section to the joint. Finite element method was used in this paper ...
