Eight curved blade stringer-stiffened composite panels were tested under axial compression to obtain the "first" buckling and postbuckling behavior till collapse. Except for one panel, used as a reference panel, all of the panels had stringers withou

It is well known [1] that non-closely stiffened panels can have considerable postbuckling reserve strength, enabling them to carry loads significantly in excess of their initial buckling load. If appropriately designed, their load carrying capacity w

Classical elasticity theory indicates that the existence of negative Poisson’s ratios (NPRs), i.e. auxetic behavior in materials, will result in an increase in shear stiffness. Motivated by the assumption of gaining potential structural benefits, t

Blade-stiffened skin designs made of composite materials have the potential to produce highly efficient structures, when the large strength reserves in the postbuckling range are utilised. This paper investigates the failure under postbuckling deform

The effective width method that is widely applied for the analysis of isotropic planar stringer-stiffened panels has been extended to laminated composite stringer-stiffened circular cylindrical panels. The approach was modified and adapted to handle

Composite aircraft structures are susceptible to impact damage during manufacture, maintenance and in-flight. Low energy impact damage is often internal and invisible, but can significantly reduce the stiffness and strength or cause catastrophic fail

Results are presented for impact tests conducted on postbuckled, thin, orthotropic carbon/epoxy laminates manufactured by the RTM process from preforms of uniweave fabric, some of which were stitched with Kevlar sewing thread. They were impacted by a

The present study is aimed at demonstrating both the capability and the relevant restrictions of piezoceramic elements (patches) to provide enough authority to control the dynamic behavior of a full size wing type structure (supposedly more rigid). T
