Detailed Description

Simple isotropic damage based model for 2d interface elements. In 2d, the interface elements are used to model contact layer between element edges. The generalized strain vector contains two relative displacements (in normal and shear direction). The generalized stress vector contains corresponding tractions in normal and tangent direction.

The behaviour of the model is elastic, described by normal and shear stiffness components. Isotropic damage is initiated when the stress reaches the tensile strength. Damage evolution is governed by normal component of generalized strain vector (normal relative displacement) by an exponential softening law.
