混凝土破坏面在主应力空间中的动态图形显示

Dynamic Graphic Expression of Concrete Failure Surface in Principal Stress Space

以 Visual C++为开发工具结合开放式图形库和微软基本类库 ,在电脑上建立三维混凝土破坏曲面 ,通过平移、旋转和裁剪三维曲面 ,实现各个角度的子午线、任意截面图甚至三维动画效果 .编制的软件有友好的界面并可用于主应力空间中各种工程材料屈服面和破坏面的模型及计算机辅助教学 .

With the development tools of visual C++, open graphic library (OpenGL) and microsoft foundation class (MFC), a kind of software on dynamic graphic expression of three-dimensional concrete failure surfaces in principal stress space was developed on personal computer. Meridians with any angle, sections at any plane and even animation can be easily realized by translating, rotating and cutting off three-dimensional failure models. The present users-friendly software can be widely used in establishing the yield and failure surfaces for various engineering materials and the computer aided instruction (CAI).
