On the Calibration of a Numerical Model for Concrete-to-Concrete Interface.

The study was devoted to the numerical modelling of concrete-to-concrete interfaces. Such an interface can be found in many modern composite structures, so proper characterisation of its behaviour is of great importance. A strategy for calibration of a model based on cohesive finite elements and the elastic-damage traction-separation constitutive law available by default in the Abaqus code was proposed.
