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 ...
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 ...
Structural overprinting and style of deformation at sierra Beauvoir and sierra de Apen: A geometric and kinematic model for the evolution of the internal thrust-fold belt, Fuegian Andes, Argentina
(Pergamon-Elsevier Science Ltd, 2021-12)
A detailed study of the structural fabrics and overprinting relationships exposed at sierra Beauvoir and sierra de Apen, which include folds, foliations and thrust faults, allowed us to settle a deformation sequence of the ...
The Alegre Lineament and its role over the tectonic evolution of the Campos Basin and adjacent continental margin, Southeastern Brazil
(Elsevier B.V., 2016-08-01)
The structural framework and tectonic evolution of the sedimentary basins along the eastern margin of the South American continent are closely associated with the tectonic framework and crustal heterogeneities inherited ...
Tooth microstructure and feeding biology of the brittle star Ophioplocus januarii (Echinodermata: Ophiuroidea) from northern Patagonia, Argentina
(Revista de Biología Tropical, 2015-06)
Ophioplocus januarii is a common brittle star on soft and hard substrates along the Argentinian and Brazilian coasts. Based on stomach contents, tooth microstructure and field observations we identified its food. Opposed ...
