Abstract

The cohesive crack model is, nowadays, widely used for the analysis of propagating cracks in concrete and other quasi-brittle materials. So far the material parameters defining this model have been considered as material properties and have been identified through the simulation of experimental tests. In this study the analysis of single notched specimens subjected to tensile loading, often used for the characterization of the fracture behavior of concrete, is analyzed on the basis of a recent meso-structural model. A procedure to obtain a macroscopic cohesive crack law from the meso-level response is outlined and the calculated macroscopic response is analyzed in order to define the actual macroscopic material properties of concrete fracture.
