An asymptotic study of the debonding of thin films Kaushik Bhattacharya Abstract: We examine the asymptotic behavior of a bilayer thin film using the notion of Gamma-convergence. We allow for debonding at the interface, but penalize it using an interfacial energy; thus the functional we consider consists of the elastic energy of the two layers and the interfacial energy with penalizes debonding. We show that the asymptotic theory or Gamma-limit depends on the particular form of the interfacial energy, and derive detailed results for both the cohesive and the brittle interface.
