Interface models are well established and frequently applied in material science. Classical non‐coherent interface models such as cohesive zone models are described by a Helmholtz energy depending on the displacement jump. The extension to thermodynamically consistent combination of classical non‐coherent cohesive zone models with surface elasticity is still relatively new, cf. [1] and [2]. These models depend on the displacement jump as well as on the surface deformation gradient. In this contribution the impact of higher‐order surface gradients is investigated.
