TENSILE AND TENSILE FATIGUE BEHAVIOUR OF CONCRETE; EXPERIMENTS, MODELLING AND ANALYSES

A model based on nonlinear fracture mechanics is presented for the fatigue behavior of plain concrete. The tensile behavior of concrete for a monotonic increasing deformation is described. The softening relation is described and the way the fracture mechanics parameters are influenced by several variables is shown. The behavior of a softening material subjected to a uniaxial tensile test is explained. Based on experimental results, a constitutive model for the crack cyclic behavior of concrete is proposed. The adequacy of the model is shown by numerical simulation of notched beams under 4-point bending. It is shown by experiments, that localization and non-uniform crack opening occurs in tensile fatigue tests just as in monotonic loaded tensile tests.
