Reliability Analysis of Laminate Composite Plate Structures
Methods formulated on the basis of the concept of first-ply failure and the structural reliability theory are presented for the reliability analysis of laminated composite plates. The first-ply failure analysis of the laminated plates is achieved via the use of different phenomenological failure criterion and the finite element method. In the reliability formulation, an appropriate phenomenological failure criterion is used to extablish the limit state equation of the laminated composite plates and different numerical techniques are employed to evaluate the reliability of the plates. Experimental investigations of lamina strengths and first-ply failure loads of laminated composite plates were performed. Base-line probability distributions of lamina strength parameters constructed from the test data are used to study the reliability of the laminated plates. The accuracy of the proposed models in reliability assessment of the laminated plates are verified by the experimental results on first-ply failure load distributions. The proposed method is used for the reliability design of laminated composite canister cover plate structures. Design and manufacture of different the cover plate structures are presented. The relability of the plate structures is investigated.
