large specimens so the LEFM conditions are possible.
The broad scale analysis of the professional literature presented in the paper has proven that fracture mechanics of concrete is worth dealing with. Each of the discussed models has its limitations. The two-parameter fracture model and size-effect model produce very similar results but at the same time there are other parameters which differ from one fracture model to another. For example, the fracture energy Gf – Hilleborg’s
