Abstract
A single unit of a composite Vee section construction was manufactured from glass reinforced polyester and has been analysed analytically and experimentally to first buckling. The composite construction was made from two components, one of which was a skeletal system and the other a continuum one. The pultruded skeletal component had a glass fibre I polyester resin matrix ratio of 65–35% weight and the hand lay-up continuum component had a glass fibre/polyester resin matrix of 30–70% by weight. The analytical analysis was undertaken by the finite element method using rectangular plate elements in combination with line elements, as proposed by Scordelis, and included buckling of the continuum and its effect on the post- buckling behaviour of the structure. The buckling mode is expressed by determining the corresponding eigen-vector.
It was found that provided the analytical modelling of the practical structure is carefully performed, good correlation is achieved between the experimental and analytical structures. In the stability analysis small displacements were assumed and it was found that the bifurcation behaviour was totally dependent upon the level of the axial stresses on the structure.
