    摘要:

    采用兩點(diǎn)概率函數(shù)提取W骨架/Zr基非晶合金復(fù)合材料的統(tǒng)計(jì)特征并重構(gòu)代表體積單元。結(jié)果顯示,兩點(diǎn)概率函數(shù)可以良好的描述復(fù)合材料的微細(xì)觀幾何結(jié)構(gòu)特征,并給出了材料呈宏觀各向同性的理論依據(jù)；獲得的代表體積單元與原材料擁有相同的幾何特征,且尺寸僅為原材料SEM圖像的2.2%,可有效提高有限元仿真的效率。該研究為W骨架/Zr基非晶合金復(fù)合材料的研究提供了有力工具。

    Abstract:

    The statistical characteristics of Zr-based metallic glass reinforced porous W matrix composite are extracted using two-point probability functions. And representative volume elements (RVE) of the composite are reconstructed. The results show that the micro-structural geometric structure characteristics can be described satisfactorily and the theoretical foundation of macro isotropy of materials is approved. Though the RVEs have the same geometric characteristics with original composites, RVEs are only 2.2% in the size of original SEM picture. Which can increases the efficiency of finite element analysis. A strong tool is developed for the research of Zr-based metallic glass reinforced porous W matrix composite by this work.
