A micro-mechanics model for imperfect interface in dielectric materials

The interface between two dielectric bodies is considered imperfect if ther e are defects (micro-voids and microcracks) present on the interface. For s uch interface, the perfect continuity condition across the interface is no longer valid and its use in analysis becomes questionable. To account for t his imperfection, we propose a micro-mechanics model based on the self-cons istent scheme, leading to the establishment of a constitutive relationship between the electric displacement and potential discontinuity across the im perfect interface.
