Sluys, L.J. Faculty Civil Engineering and Geosciences Department Mechanics, Materials and Structures Date 2001-01-01 Abstract Embedded discontinuity formulations have been recently presented as a method of incorporating displacement discontinuities in standard finite elements. These elements allow inelastic deformations to be modelled using discrete constitutive models at an internal interface. However, the actual formulation of these models is identical in concept to more traditional fracture energy regularised smeared crack models. Rather than adjusting the hardening modulus depending on element size, the inelastic strain itself is made dependent on element size. It is shown here that the embedded discontinuity idea and smeared crack models are conceptually identical.
