In this paper, corrosion-induced damage is investigated by means of numerical simulations utilizing a coupled lattice and finite element method (FEM) modelling approach. While the reinforcement and corrosion product domain are discretized by the FEM, a lattice approach is used for the discretization. To determine the nodal displacements and subsequently the stresses in the elements of the lattice for each analysis step, an elastic analysis is performed. Nodal displacements are obtained for a set of linear equations within a FEM formulation, where the global nodal force vector {F} relates to the global stiffness matrix [K] and the global nodal displacement vector {U}. In this modeling approach, combinations of lattice and continuum elements are used to discretize the various domains, with truss elements for the concrete domain and bilinear quadratic elements for the corrosion products and linear triangular elements for reinforcement. The resultant stiffness matrices are defined for truss elements in the concrete domain and for linear triangular elements in the steel domain, providing a comprehensive framework for simulating corrosion-induced concrete damage.
