PROBLEM OF DELAMINATION IN RC BEAMS STRENGTHENED BY FRP WITH RHEOLOGICAL MODEL OF ADHESIVE LEYER
Journal Title: Civil and Environmental Engineering Reports - Year 2016, Vol 4, Issue 23
Abstract
This paper deals with one of the most dangerous failure modes in layered structures, namely delamination. The strengthening layer is modelled by a solid-shell finite element. The mechanical modelling of delamination onset and propagation is based upon a cohesive zone model implemented into a cohesive element located between adhesive layer and a concrete structure. The long time behavior of epoxy adhesive layer is modelled with the five-parameter rheological model.The numerical simulations are accomplished within the commercial software package Abaqus by the implementation of a user-written finite element and user-written material.
