摘要:

越來越多的研究發現增強體空間構型分布有望成為金屬基復合材料強韌性倒置問題的有效解決辦法。然而，構型設計要素種類繁多，除傳統結構設計要素外，還包括增強體分布特征等結構參數。因此，僅靠傳統的實驗手段已無法滿足復合材料構型設計的研究需求，借助有限元模擬探索各構型要素對復合材料性能的影響規律可作為試驗研究的前提和有效補充。基于三維幾何模型的有限元模擬技術，將增強體分布特征引入復合材料三維幾何模型中，再引入各組分的物理及力學性能，則能夠對構型化復合材料的變形與斷裂行為進行模擬，并預測其力學性能。首先回顧了數值模擬顆粒增強金屬基復合材料的幾何和數值模型構建方法，然后對網狀結構構型化復合材料有限元模擬工作的研究現狀進行了介紹，最后對構型化復合材料有限元模擬工作的未來發展進行了展望。

Abstract:

Recently, it was proved that tailoring the reinforcement distribution is expected to overcome the contradiction between the strength and toughness of metal matrix composites (MMCs). However, the architectural design includes many factors, i.e. reinforcement size, shape and types as well as structural parameters. Thus, traditional experimental methods can’t meet the research demand of architectural design, and consequently, investigating the effect of structural factors on the properties of the composites via finite element method (FEM) becomes a necessity. Through building three-dimensional geometric models and introduing constitutive laws of matrix, reforcement and interface, one can predict deformation/failure behaviors and mechanical properties of composites with a range of tailored architectures. In this paper, the modeling process of particle reinforced MMCs was firstly reviewed. Then the research progress of FEM simulation on composites with network architectures was presented following by an outlook to the future of FEM simulation on composite with various architectures.
