English abstract:
A numerically efficient approach for the prediction of consecutive growth of delaminations with curved fronts is developed. The approach is based on the assumption that the delamination grows from its current front to a predefined advanced front and that the delamination
front remains smooth during the entire growth process. For computation of the load required to propagate the delamination the finite element method and the virtual crack closure technique are employed and incremental growth is predicted. As an example, delamination
growth in a laminated plate is analyzed.
