This work consists in the development of a numerical model
in order to simulate the fracture process in concrete
structures. This model is supported by concepts of the
Finite Element Method and the Fracture Mechanics applied to
concrete. The main keyword which characterizes this work is
interface element. This finite element permits the
modelling of discontinuities in the finite element mesh
among the edges of the elements. In this work, these
elements are used to represent cracks in concrete
structures. The cracks modelling is supported by the
discrete crack concept, which is associated to a
constitutive model called elastic-softening, specific for
the crack or for the interface element. In this work, the
nonlinear analyses were limited to structural systems under
fracture mode I.This work consists in the development of a
