| Abstract: |
| Ultimate Tensile Strength (UTS) of composite materials is influenced by the variation in fiber strength and randomness of fibers' distribution.A shear-lag numerical model,which depends on a reasonable hypothesis of fiber distribution,is built in this paper.A Monte-Carlo simulation using current model is used to analyze the failure process of uni-directional composites and obtain the UTS.Compared with model from literature,current model obtains much more perfect results. |
