Abstract [en]

The inner softening band approach is used to model the mixed mode (mode I and II) cracking of concrete. The softening behaviour is attributed to a displacement discontinuity within an element. The constitutive relation between tractions and relative displacements is based on the Mohr-Coulomb criterion with tension cut-off. Softening affects both the tensile strength and the cohesion of the material. The cracking pattern is controlled by an energy criterion leading to fairly unique results. Some numerical examples show that the results are objective and independent, to a certain degree, on finite element mesh
