On the use of high aspect ratio finite elements to model hydraulic fracturing in deformable porous media
(2019-06-15)
Hydraulic fracturing is a technique based on the injection of a viscous fluid at high pressure into an engineered well with the intention of initiating and propagating multiple fractures in a rock formation containing ...
Modeling of interfaces in two-dimensional problems using solid finite elements with high aspect ratio
(Pergamon-Elsevier B.V. Ltd, 2012-03-01)
The use of standard solid finite elements with a very high aspect ratio is proposed to model the behavior of thin interface regions between distinct components of composite structural members. It is shown that these elements ...
On the use of finite elements with a high aspect ratio for modeling cracks in quasi-brittle materials
(2016-03-01)
A new technique for modeling cracks in quasi-brittle materials based on the use of interface solid finite elements is presented. This strategy named mesh fragmentation technique consists in introducing sets of standard ...

Modeling of multiple cracks in reinforced concrete members using solid finite elements with high aspect ratio
(Crc Press-taylor & Francis Group, 2014-01-01)
This paper presents a new technique to model interfaces by means of degenerated solid finite elements, i.e., elements with a very high aspect ratio, with the smallest dimension corresponding to the thickness of the interfaces. ...

Hydro-mechanical coupled modeling of hydraulic fracturing using the mesh fragmentation technique
(2020-08-01)
The inclusion of special interface elements between standard finite elements is becoming a common technique to model discontinuities in porous media using the finite element method (FEM). Recently, it was proved that high ...
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 ...
