“…First in Section 2, the computational model in terms of mechanical energies is described and governing relations for its energy state evolution are formulated. The present model is based on previous works of the research group which were initiated in a brittle interface debonding model of [16], subsequently updated to the models with interface cohesive zones in [17], [18], [19], and newly extended for phase-field modelling as described in [20]. Then in Section 3, the behaviour of the presented model is documented in a couple of numerical tests which contain analysed domain with an inclusion.…”
