本文较为广泛地探讨了光学方法在复合材料力学中的应用。根据几种近代光学方法的各自特点与长处,较全面地、成功地分别应用到复合材料构件的位移、应变和应力测量上。结果表明,光学方法是复合材料力学研究中的一种十分有效的手段,它为许多迄今难以解决的问题提供了可靠而准确的求解方法。 This article discusses the application of optical methods in the mechanics of composites. According to the characteristics and merits of several modern optical methods, they are applied to the displacement, strain and stress measurement of composite materials more comprehensively and successfully. The results show that the optical method is a very effective method in the mechanics of composites, which provides a reliable and accurate solution to many problems that so far have not been solved.
