Modelling of three-point bending test of beams with steel inclusion situated in the middle of the span

Abstract

The aim of this paper is to present the numerical model of the fracture response of the test specimens with a steel inclusion in the shape of the prisms which length is equal to the specimen’s width. Specially designed fine-grained cement-based matrix specimens of the nominal dimension 40 x 40 x 160mm with inclusion of 8 x 8 x 40mm and central edge notch serves to determine of the influence of the interfacial transition zone on the effective mechanical fracture parameters of composite. The numerical models of three-point bending test of these specimens are created in ATENA software.
