Optical experimental techniques for characterizing matrix crack-inclusion interaction of composite materials:A Review
Due to the demanding service environments,engineering materials with more than one phase and exploit beneficial characteristics of individual constituents to achieve the desired over all properties have become a common practice.How the inclusions(or second phase)influence the stress field in matrix crack of composites is an important and difficult problem.Optical experimental techniques,as a full field,noncontact method of experimental mechanics,are widely used in engineering testing with the development of modern optical measurement mechanics and computer technology.In this paper,the basic principle of caustics,digital gradient sensing(DGS),and photoelasticity were introduced,and their application in the matrix crack-inclusion interaction of composites were summarized.Finally,the bottleneck problems in the application of optical experimental techniques in mechanics of composite materials were discussed.Some suggestions in the application of optical experimental techniques in mechanics of composite materials were put forward in consideration of the characteristics of mechanical performance of composites.
