Monte Carlo Simulation of the Strength of Hybrid Composites

This paper first deals with the stress concentration factors for a general fiber breakage model. The knowledge of stress redistribution at fiber fracture is then used for a Monte Carlo simulation of composite strength. The theoretical analysis has predicted the multiple fracture pattern of the low elongation fibers and the progressive nature of failure of hybrid composites. The enhanced ultimate failure strain of the hybrid as compared with that of the low elongation fiber composites signifies a hybrid effect. The major fin dings of this theoretical analysis coincide well with experimental observa tions.
