摘要
提出图形计算力学的概念和方法,将计算力学、计算机图形学和现代AutoCAD技术相融合,利用已经发展的比较完备的计算机图形学的理论方法和现代AutoCAD技术提供的三维建模平台,将整个岩体切割成为具有一定方向、一定规模、一定形态和特征面的组合实体,这种图形实体的主要特征、属性、相互接触,嵌入的位置和量值可直接从图形中判断计算。将该算法应用于多种数值方法中,较现有的纯数值计算方法更加直观、简便和可靠,此法和虚拟现实技术相结合,使图形计算力学充满了发展的空间和应用价值。
The concept and method of graphics computational mechanics which integrates computational mechanics, computer graphics and modem AutoCAD technology, are proposed firstly. By making use of the mature theory, method of computer graphics and 3D modeling platform supported by modem AutoCAD technology, the rock can be cut into combination entities of a certain direction, a certain size, a certain shape and feature. The analysis of discontinuous deformation characteristics, such as main features of the graphical entities, attributes, mutual contacts, the embedded location and extent can be directly judged or calculated from the graphics. And then it can be applied to a variety of numerical methods. Compared with the existing methods, it is more intuitive, simple and reliable. Its combination with virtual reality technology will make the graphics computational mechanics a whole new area of development and greater value of its applications.
