Simulating discontinuities in a gradient-enhanced continuum
(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, ...
Discontinuous modelling of crack propagation in a gradient-enhanced continuum
(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 ...
Discontinuities in regularised media
(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 ...
A novel technique for modelling interfaces in reinforced brittle materials
(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 ...
