Original Abstract

Tensile failure in quasi-brittle materials is connected with formation and evolution of what is referred to as the Fracture Process Zone (FPZ) at the tip of propagating crack. Not only the very existence of the material damage area but also its descriptive parameters (volume, shape and energy dissipation distribution) have to be identified in order to validate approaches on both numerical modelling of quasi-brittle behaviour and experimental determination of fracture properties. Radiographic techniques and Digital Image Correlation method are used in the presented research as being very appropriate for analysing of the FPZ evolution during specimen loading. The experimental results are accompanied with predictions of the FPZ size and shape via semi-analytical technique serving as a part of developing comprehensive method for evaluation of the real fracture-mechanical characteristics of quasi-brittle materials from records of loading tests on laboratory-sized specimens.
