A method of evaluating effective failure path of multiple layer composites laminates under off-axial load condition is presented. It is necessary to select the important failure path whose occurence probabilities are greater than the others since the number of failure path of multiple layer composite laminate is great deal of number of combination of failure path. The proposed procedure of selecting effective failure path depends upon the branch and bound rule. An extended study is examined in order to estimate the failure probability of laminate from resultant effective failure path. Some numerical analysis based on the proposed algorithm are represented to graphite/epoxy composites laminates (T300/5208).
