Abstract

A general one-dimensional model of a composite delaminated elongated strip (wide beam) under arbitrary axial and transverse loading and boundary conditions is used for predicting the classical buckling load, with the bending-stretching coupling effect as well as the prebuckling geometrical nonlinearity taken into account. The differential equations are solved by Newton's method, using a finite-difference scheme. The contribution of the coupling effect is examined by means of parametric analysis.
