A boundary element method formulation to capture strong discontinuities in solids
(2005-12-01)
A Boundary Element Method (BEM) formulation to predict the behavior of solids exhibiting displacement (strong) discontinuity is presented. In this formulation, the effects of the displacement jump of a discontinuity interface ...
A comparative study on finite elements for capturing strong discontinuities: E-FEM vs X-FEM
(Elsevier Science Sa, 2006-12)
A comparative study on finite elements for capturing strong discontinuities by means of elemental (E-FEM) or nodal enrichments (XFEM) is presented. Based on the same constitutive model (continuum damage) and linear elements ...
SUPG and discontinuity-capturing methods for coupled fluid mechanics and electrochemical transport problems
(Springer, 2013-02)
Electrophoresis is the motion of charged particles relative to the surrounding liquid under the influence of an external electric field. This electrochemical transport process is used in many scientific and technological ...
A finite element method based on capturing operator applied to wave propagation modeling
(ElsevierBrasilNúcleo Interdisciplinar de Dinâmica dos Fluidos, 2019)
A porous-based discontinuous model for ductile fracture in metals
(Elsevier, 2015-04)
A discontinuous model aimed at modeling ductile fracture for metals is presented. The effect of microvoid nucleation, growth and coalescence on the inelastic response of structural metals is modeled through a suitable ...
Stabilized discontinuous Galerkin method for hyperbolic equations

Transverse and longitudinal fluid flow modelling in fractured porous media with non-matching meshes
(2021-01-01)
A new discrete fracture model is introduced to simulate the steady-state fluid flow in discontinuous porous media. The formulation uses a multi-layered approach to capture the effect of both longitudinal and transverse ...
Crack-path field and strain-injection techniques in computational modeling of propagating material failure
(Elsevier, 2014-01)
The work presents two new numerical techniques devised for modeling propagating material failure, i.e. cracks in fracture mechanics or slip-lines in soil mechanics. The first one is termed crack-path-field technique and ...
Modelling crack growth in quasi-brittle materials using mesh fragmentation technique
(Univ Sevilla, 2015-01-01)
The modelling of discontinuities with new finite element techniques (X-FEM and E-FEM) is cumbersome due to the need of algorithm tracking to simulate the crack growth. Therefore, a new technique to capture strong discontinuities ...
Experimental and numerical cyclic response of RC walls with openings
(Elsevier, 2019)
According to Chilean design practice, walls usually have complex geometries and discontinuities in height, mainly in the first story. However, the Chilean design code, similar to many design codes, does not provide special ...
