Abstract
Studies about the reliability of fibre reinforced laminated structures have mostly concentrated on single layers with simple failure criteria such as the well known by Tsai/Wu. In laminated structures failure frequently is defined as interfibre failure. A realistic criterion taking account of the multi-axial stress states has recently been proposed by Hashin and Puck. This criterion is briefly discussed and related to energy considerations. The criterion then is used in the analysis of a realistic tube structure whose laminate stresses are determined by classical laminate theory. Reliabilities are determined by FORM methods. Correlations among the various failure modes and between the elements of the FEM-model for the tube are taken into account. The size effect is studied with particular reference to the meshing.
