An incremental symmetric boundary integral formulation for the problem of bodies connected by non-linear cohesive interface is here presented. The numerical solution example of the incremental problem is achieved by the symmetric Galerkin boundary element method (SGBEM). Numerical results of FRP-concrete delamination failure, obtained by coupling the incremental SGBEM system with a local arc-length constraint, are presented and compared with the FEM solution.

Keywords:  Boundary integral equations; Cohesive interface; Arc-length; SGBEM
