Plates, Shells and Their Composite Structures
Abstract: Review of the impact of large nonlinear deformations on plate and shell response. The approach ofmodelling discrete reinforcements and the smeared stiffeners technique suited to stringers with tightspacing are both presented in relation to the analysis of stiffened plates and shells. The behaviour andstrength of plates and shells are demonstrated to be affected by apertures and cut-outs, both locallythrough the localization of stress and globally through the effects on stiffness. …
