What is Cohesive Interaction in Concrete Structures about?
This document provides guidance on defining a cohesive interaction property in Abaqus to model the bond between concrete and FRP sheets. It outlines the steps to: 1) define the interaction property with a bilinear traction-separation curve, 2) calculate stiffness parameters for the normal and shear directions, and 3) define damage initiation and evolution criteria based on tensile strength and fracture energies of the materials. The interaction is created by selecting the stiffer FRP sheet as the master sur
