产品虚拟设计中的复相材料显微组织模型设计

材料是先进制造技术中的有机组合部分，材料显微组织虚拟设计则是虚拟制造技术中的重要内容之一。采用计算机图形技术设计了包括复合材料在内的一系列显微组织模型，其中部分模型可以借助Ｍｏｎｔｅ Ｃａｒｌｏ仿真技术进行了动态演变，以模拟真实的物理冶金过程，并能定量预报某些显微组织演变的动力学特征。根据性能要求设计的，优化的复合材料显微组织，可望用作材料细观力学设计的组织几何模型。

Modeling and Design of Multi-Phased Microstructures in Virtual Product Design

Material-design is indispensable to advanced manufacture technology, while the virtual design of microstructure of materials is one of the essential components in virtual product design. In the present work, the advanced computer technology is applied to design a series of microstructure models including those of composite materials. Especially, some of the models are established with aids of Monte Carlo simulation, the evolution process of such model-microstructures can be used to simulate the real physical-metallurgy processes and to predict quantitative dynamic information of the evolution of microstructures. It is expected that the quantitative characteristics of such visual microstructure models can be used as inputs of meso-scale mechanics calculation in material-design.
