Virtual 3D nonlinear simulation of uniaxial tension test of concrete

Virtual 3D nonlinear simulation of uniaxial tension test of concrete

Paper in proceedings (conference paper)

The paper shows possibilities of nonlinear fracture mechanics simulation to capture results of uniaxial tension experiments and discuss problematic aspects of modelling. The occurence of secondary flexure is a fundamental problem studied experimentally by third autor. The virtual 3D numerical simulation of those experiments eliminating/leaving secondary flexure was performed. The aim of modelling is to given a better insight into uniaxial tension behavior which cannot be obtained directly from experiments including the formation of fracture process zone, the influence of load eccentricity and heterogeneity of concrete.
