      abstract     = {During constrained sintering of thin films, in which a
                      cylindrical cavity with axis perpendicular to the substrate
                      has been introduced before sintering, cracks emerge that
                      initiate at the cavity surface. By combining experiments
                      with continuum mechanical and particle based simulations,
                      the fundamental causes and effects of this kind of crack
                      formation are identified. A stress analysis performed by
                      finite element (FEM) simulations matches with the cracking
                      behavior observed in experiments. A comparison of discrete
                      element (DEM) results with experiments shows the
                      applicability of this simulation method to describe the
                      effect of cross-sectional stripe dimensions and cavity
                      diameters on the cracking behavior. Moreover, DEM
                      simulations reveal that hair-line cracks in narrow stripe
                      samples formed during pre-sintering manufacturing steps
                      might be a dominant cause for the observed crack damage in
                      such systems},
