Abstract
In this paper, the calibration of a cohesive zone model in front of a crack is presented. It is based on the behavior of a cell containing a void. The sizes of the cell and the void are assumed to be representative for a chosen material. The cell is located at the crack tip. The loading conditions of the cell take into account the constraint level ahead of the crack tip. The influence of the constraint on the cohesive model parameters is investigated.
