不确定微观结构复合材料的随机均匀化热性质
Stochastic homogenized thermal properties of composites with an uncertain microstructure
摘要
Abstract
Random homogenization analysis of the effective thermal properties of a three‐dimensional composite material with unidirectional fibers is presented by combining the equivalent inclusion method with the Random Factor Method ( RFM ) . The randomness of the micro‐structural morphology and constituent material properties as well as the correlation among these random parameters are completely accounted for , and stochastic effective thermal properties as thermal expansion coefficients as well as their correlation are then found . Results from the RFM and the Monte‐Carlo Method ( MCM ) are compared . The impact of randomness and correlation of the micro‐structural parameters on the random homogenized results is revealed by two methods simultaneously , with some important conclusions obtained .关键词
