  • A novel technique for modelling interfaces in reinforced brittle materials 

    Simone, A; Wells, Garth Nathan; Sluys, LJ (Proceedings of the 4th International Conference on Fracture Mechanics of Concrete Structures (FRAMCOS4)Proceedings of the 4th International Conference on Fracture Mechanics of Concrete Structures (FRAMCOS4), 2001)
    A novel numerical technique for the modelling of interfaces is introduced for the analysis of reinforced brittle materials. The method exploits the partition of unity property of finite element shape functions. By considering ...

  • An interface element based on the partition of unity 

    Simone, A; Remmers, Joris J C; Wells, G N (Delft University of Technology, 2001)
    An alternative interface finite element is developed. By using the partition of unity property of finite element shape functions, discontinuous shape functions are added to the standard finite element basis. The interface ...

  • Discontinuities in regularised media 

    Simone, A; Wells, Garth Nathan; Sluys, LJ (2003)
    Discontinuous interpolation of the problem fields in non-local and rate-dependent media is considered. The necessity of discontinuities in the analysis of failure processes and some of the requirements for the introduction ...

  • Discontinuous modelling of crack propagation in a gradient-enhanced continuum 

    Simone, A; Wells, Garth Nathan; Sluys, LJ (2002)
    A numerical model for the description of the combined continuous/discontinuous failure in a regularised strain-softening continuum is proposed. The continuum is regularised through the introduction of gradient terms into ...

  • Simulating discontinuities in a gradient-enhanced continuum 

    Simone, A; Wells, Garth Nathan; Sluys, LJ (Proceedings of the International Conference on Structural Integrity and FractureProceedings of the International Conference on Structural Integrity and Fracture, 2002)
    A continuum-discrete model for failure in quasi-brittle materials is presented. The continuum is regularised through the introduction of gradient terms into the constitutive model. At the transition to discrete failure, ...
