809 画像解析によるコンクリートの破壊進行過程の計測と可視化に関する基礎的研究(OS8-(3),OS8 オーガナイズドセッション《複合材料の変形と破壊およびマルチスケール計算技術》)

Abstract

It is well known that cement-based materials form the fracture process zone near crack tip due to material inhomogeneity. It is important that we consider the fracture behavior in fracture process zone because it affects the strength and toughness of materials. In this study, we develop image analysis methods to visualize the fracture process zone in concrete by using the image correlation method. We compare the image analysis results with the experimental result to examine the validity of the present method. To easily understand the fracture behavior in fracture process zone, an experiment using mortar test piece was carried out.
