Mixed mode fracture in plain and reinforced concrete: some results on benchmark tests

Three different models for concrete based on local and non-local approaches have been adopted to investigate the mechanical behaviour of plain and rei nforced concrete when undergoing mixed-mode fracture. The purpose of the re search is to understand the results of some benchmark tests, to compare the models with each other and with experiments, and to estimate the reliabili ty of the modelling. To create a sound basis for the comparison, the discre tizations, the boundary conditions and the material data are considered, wh en possible, as unified parameters for the different models in each benchma rk test.
