摘要:
以Visual C++.NET为开发工具，将面向对象编程技术引入到数字散斑相关方法中,对所开发的程序通过计算机模拟和实验两个方面进行了有效性的验证。应用开发的程序计算斜接头指接集成材受拉伸作用时的变形规律，结果表明被测试件在受到拉伸作用时，同一表面两边的位移量大于中间部位的位移量；对于一个整的齿面，齿顶的变形较根部的变形大，而且顺木材纹理方向与垂直木材纹理方向呈现出不同的变形规律。散斑相关计算木材生长方向的泊松比μLT为0.1～0.3。西北林学院学报22卷第3期刘美华等数字散斑相关在指接集成材力学性能测试中的应用
Abstract:
A program objectoriented to digital speckle correlation method via Visual C++.NET is introduced and classlibrary of digital correlation program by adopting standard C++ developed. At the same time, a program frame utilized to manage and run these classes was developed as well. The validity of the program was verified through numerical simulation and experiment. The program was used for deformation law of fingerlike diagonal joint of wood in tension. The results indicated that deformation in the root was larger than in the top of teeth and deformation laws were different in parallel and vertical direction to wood grain.
