Modelling steel-concrete interaction using the extended finite element method

The extended finite element method (X-FEM) is used as an alternative for the modelling of the bond behaviour between reinforcement and the surrounding concrete in reinforced concrete structures, through either reinforcing bars, fibres or others. The interface of composite materials introduces a disc...
