On elastic clamping boundary conditions in plate models describing detaching bilayers

Elastic clamping boundary conditions are derived, which describe root rotations and displacements in plate models used to analyze detaching bimaterial layers subjected arbitrary end loadings. The elasticity technique uses the reciprocity theorem J-integral calculations is applicable isotropic orthotropic of different thicknesses, also with extreme elastic constants mismatch.
