| Abstract: | A homogenization- based methed is presented for predicting the thermal expansioncoefficients of composites,The formulation of microhomogenization problem caused by thismethed,and the schemes to solve this problem using finite element method are given. Asexamples,the thermal expansion coefficients of two kinds of materials are predicted.The resultsobtained are in good agreement with results of other analytical method in literature,and withexperimental data. |
