The mechanisms and structural parameters affecting the interlaminar stress field in laminates with ply drop-offs have been investigated to help better understand the effects of different parameters in such laminates. Based on equilibrium consideratio

The transverse loading response of convex composite shell structures typical of aircraft fuselage sections was investigated, and the experimental work is reported. Important mechanisms in the response, particularly instabilities (buckling), were stud

The response of transversely point-loaded composite shells is investigated via the finite element method. The thin, circular cylindrical shells are hinged at a fixed distance apart on the straight edges and are free on the curved edges. Stability iss

Interlaminar stresses that arise in composite laminates where gradients exist in in-plane stress fields are investigated. Two distinct mechanisms give rise to interlaminar stresses in generic problems, the presence of free edges and in-plane gradient

The transverse-loading response of laminated composite shell structures is studied experimentally and numerically. Monolithic graphite/epoxy shell structures having layups of [§ 45n/0n]s (n= 1;2;and3) closely represent commercial fuselage structures

The impact and quasi-static response of various composite shell structures to transverse loading was studied experimentally. In particular, the effect of varying structural parameters (radius, span, and thickness) on the loading response, including d

The role of modeling in the design of structural composite components against failure is discussed. Composite materials fail due to damage processes operating at several lengthscales. The interactions between these processes offer the principal chall

Journal of Applied Mechanics. 64:401-407
The effects of geometric nonlinearity on the response of axially cracked cylindrical shells under internal pressure are investigated in a general way. Using the Donnell-Mushtari-Vlasov nonlinear shell equations, the nonlinear response is shown to dep
