A review of selected results pertaining to mathematically one dimensional edge debonding is presented for structural configurations corresponding to patched plates under applied in-plane tension, and patched cylindrical panels under applied (internal) pressure. The effects of relative stiffness and relative length of the patch with respect to those of the base structure are examined and compared. The problems are approached from a unified point of view, as moving interior boundaries problems in the calculus of variations, resulting in self consistent models of the intact and debonded segments of the composite structures, the individual primitive structures, and the corresponding conditions which define the intermediate boundaries of the bonded region and a region of sliding contact. Numerical simulations based on analytical solutions demonstrate characteristic behaviour of the evolving structures under load.
