    • Abstract
  • A kind of homogenized numerical model of woven fabric composite material is presented, which provides a simpler and more accurate numerical method for engineering applications. At first, a cell model with fine FE mesh is established for the representative cell of the woven fabric composite material. And then the results of the FE analysis of the cell model are introduced into the three dimensional penalty equilibrating element based on the Hu-Washizu variational principle. In this way, a kind of woven fabric composite material with meso-structure can be formulated as the equivalent homogenized element, which can be applied in macro-structural analysis. Numerical examples are given to compare the results obtained by the present approach with experimental and other numerical results, and to show the efficiency and applicability of the present numerical method.
