Abstract

In this paper, the experimental model for the toughening of brittle matrixes with ductile particles is proposed. The specimens are made from polymethyl methacrylate (PMMA) , rubber particles were embedded in crack front of specimen. Using holographic photoelasticity method, we make a lot of test, and obtain many photographs of isoline of stress sum. The stress intensity factor Ki is calculated from extrapolation of maximum diameter of isoline of stress sum (isopachics), and compared with theoretical values.
