Original Abstract

The paper proposes a method for determination of the fracture process zone (FPZ) width in cementitious composites by means of nano/micro-indentation tests. The FPZ width was assessed from changes in (micro-) mechanical parameters on side surfaces of a test specimen close to a crack propagated in the specimen during the fracture test (three point bending). The experimental work was conducted in order to validate a suggested analytical method for estimation of the FPZ's size and shape. The pilot indentation experiment demonstrated the feasibility of the proposed experimental method.
