摘要
随着现代光电子和计算机技术的发展以及数字图像处理理论的深入 ,数字散斑相关方法 (DSCM )迅速成为实验力学领域一种重要的测试方法。文章介绍了DSCM的基本原理 ,并对其在木材科学领域的应用进行了综述 ,包括在木材常规力学测试和木材断裂、微观力学以及复合材料力学测试等方面的应用及一些新的成果。最后根据木材材料的特点 。
With the development of the technologies on modern photoelectron and computer technologies and the improvement on theory of digital image processing, Digital Speckle Correlation Method(DSCM)is rapidly emerging as a powerful research tool for experimental mechanics techniques. In this paper, the essential principle of DSCM is introduced and the applications of DSCM to wood science and technology, including the latest results of the test on general mechanical properties, fracture properties, micro structural mechanical properties and the mechanical properties of wood and wood composite materials, are reviewed. Considering the characteristics of wood materials, some suggestions are proposed on the application of DSCM to wood science and technology.
