Abstract In this work, the finite element method (FEM) was used, in conjunction with experiments, to study some of the crack patterns observed during the indentation of coated systems. In particular, the study was centered on the array of circular cracks observed close to the contact edge of the spherical indentations of systems with soft substrates. A sequence of steps was considered during the FEM formulation. Initially, the deposition (intrinsic) and thermal (extrinsic) stresses were… CONTINUE READING
