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 ...

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 ...

A new approach for concurrent multiscale modeling of three-dimensional crack propagation in concrete is proposed. A macroscopic model with homogenized elastic parameters is adopted in the regions where the material behaves ...

We present a numerical technique capable of handling evolving fractures in rocks triggered by coupled thermo-hydro-mechanical (THM) phenomena. The approach is formulated in the context of the finite-element method (FEM) ...

A multiscale model is proposed based on the use of coupling finite elements recently developed by the authors. This feature allows the use of the same strategy to deal with two problems of non-matching meshes addressed in ...

The problem of desiccation cracks in soils has received increasing attention in the last few years, in both experimental investigations and modeling. Experimental research has been mainly focused on the behavior of slurries ...

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 ...
