000021475 520__ $$2eng$$aConcrete and other cementitious materials are undoubtedly the most important and widely used construction material nowadays. However, there exist other building materials, such as wood or composites, which are on high demand as well. Different mathematical models describing the complex material behaviour of these mostly quasi-brittle materials are used. Their application often requires the knowledge of experimentally determined fracture properties of studied material. The total fracture energy can be often determined directly from experimental measurements as the total work divided by the ligament area. However, the determination of true tensile strength and the traction-separation diagram is usually problematic. The primary objective of this paper is to present a numerical scheme, that can be used to determine the traction-separation diagram in the framework of sequentially linear analysis (SLA).
