On the basis of experimental data on the fracture of an adhesive layer mating two plates along a given section and the known analytical solution corresponding to the calculation scheme, variants of the fracture criterion that take into account hydrostatic pressure and invariant components of elastic energy are considered. One- and two-parameter criteria are investigated, in which the products of volume and shape deformation energy per layer thickness form the critical flow of elastic energy density. It is shown that the loosening of a thin adhesive layer under a two-parameter criterion quasilinear with respect to the volume strain energy most accurately describes the critical state.
