Original Abstract

Cement-based composites are traditionally used building materials. Concrete is the basic representa-tive of this type of materials which exhibit the so called quasi-brittle response. Quantification of mechanical fracture parameters is performed using fracture tests on specimens with a stress concen-trator. Load versus crack mouth opening displacement (P–CMOD) diagrams are recorded during these tests. In order correctly to evaluate these diagrams an advanced own developed software tool was used for the data filtering and appropriate modifications. In this paper, the programmed Java utility is generally introduced and its utilization demonstrated on the set of recorded P–CMOD dia-grams, which are further evaluated using Double-K fracture model.
