  • 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 ...

  • Strong embedded discontinuities for simulating fracture in quasi-brittle materials 

    Alfaiate, J; Wells, Garth Nathan; Sluys, LJ (Fracture Mechanics of Concrete StructuresFracture Mechanics of Concrete Structures, 2001)
    In this paper embedded strong discontinuities are used to model discrete cracking in materials like concrete. In the approach followed a discontinuous displacement field is considered and the deformation is localized at a ...

  • Time scale in concrete fracture: a model based on partitions of unity 

    Van Zijl, GPA; Wells, Garth Nathan (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)
    Intense research efforts have been put in the formulation of theories for crack initiation and propagation in concrete. Yet, little attention has been paid to the time-dependence of fracture, despite evidence of its ...
