**Abstract**
 The objective of this work was to find a solution to the cohesive damaged zone that may occur at the interface between a fibre reinforced polymer plate and concrete structure, when considering elastic deformation in the substrate. The structure incorporates a structural adhesive. The work aims to provide data to be used in civil engineering applications such as infrastructure retrofit and repair. For this purpose, the procedure was that a two-dimensional cohesive layer constitutive model with a prescribed traction-separation law was constructed from basic principles of continuum mechanics. Detailed benchmark comparisons of analytical results with finite element predictions for a double cantilever beam specimen were performed for model verification, and issues related to cohesive layer thickness were investigated. It was observed that the assumption of a rigid substrate in analytical modelling could lead to inaccurate analytical prediction of the cohesive damage zone length. 10 refs.
