Automated modelling of viscoelastic flow using FEniCS
(XVI Convegno Italiano di Meccanica ComputazionaleXVI Convegno Italiano di Meccanica Computazionale, 2006)
Using high-level abstractions, it is possible to efﬁciently automate the development of ﬁnite element models. This has advantages in terms of rapid development, a dramatic reduction in programming errors and offers the ...
A study of discontinuous Galerkin methods for thin bending problems
(Computational Mechanics: Solids Structures and Coupled ProblemsComputational Mechanics: Solids Structures and Coupled Problems, 2006)
Various continuous/discontinuous Galerkin formulations are examined for the analysis of thin plates. These methods rely on weak imposition of continuity of the normal slope across element boundaries. We draw here upon ...
Application of continuum laws in discontinuity analysis based on a regularised displacement jump
(Proceedings of the European Conference on Computational Mechanics ECCM '99Proceedings of the European Conference on Computational Mechanics ECCM '99, 1999)
The application of continuum constitutive laws in embedded strong discontinuity analysis is examined. By adopting a regularised discontinuity (approximating the unbounded strain field resulting from a displacement jump ...
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 ...
