Mean field homogenization methods for strand composites

In this work, we present a hybrid method for predicting the stiffness of strand composites by using a combination of finite element and analytic mean field homogenization techniques. The proposed model combines the versatility of finite element models and the ease of computation of analytic schemes. This method can be used to model strands of any shape and orientation distribution; it also presents possibilities for detailed parametric analysis. The proposed method yields predictions that are consistent with experimental measurements and provides insights about testing protocols and observed scatter in experimental results.
