| Abstract: | Based on energy equivalence Principle, a finite element stochastic on-ergy method is presented to predict the mechanical properties of short fiber composite materials. The method is a combined method of the finite ele-ment method with Monte carlo stochastic sampling method.Some theoretical predicting results of mechanical properties of Carbon/AG3, Carbon/AG321 and Steel/Urethane as numerical examples are given in the paper.The agr-eement of the numerical predicting results with experimental results shows that the model and method provided in the paper is reasonable and effec-tive. |
