The paper studies well published results of direct tensile tests on dog-bone specimens with rotating boundary conditions performed by van Vliet and van Mier [

]. In particular we are interested in the series of dry concrete specimens A to F (dimension D varying from 50 to 1600 mm, see Fig. 1); a series accompanied by verification tensile splitting tests. The paper attempts at explaining of the complex size effect on mean and variance of nominal strength by combination of random field simulation of local material properties, “weak boundary” effects and a nonlinear fracture mechanics software based on a cohesive crack model.
