      Aortic Coarctation is a congenital constriction of the aorta that increases blood pressure above the constriction and hinders the flow below it. Based on a 3D surface mesh of a moderate thoracic coarctation, a high quality ...
    • Anisotropic microsphere-based approach to damage in soft fibered tissue 

      Sáez Viñas, Pablo; Alastrué, V.; Pena, Estefania; Doblaré, Manuel; Martínez, Miguel Ángel (2012-05)
      Article
      Accés obert
      An anisotropic damage model for soft fibered tissue is presented in this paper, using a multi-scale scheme and focusing on the directionally dependent behavior of these materials. For this purpose, a micro-structural or, ...
    • Hybrid model for vascular tree structures 

      Puig Puig, Anna; Tost Pardell, Daniela; Navazo Álvaro, Isabel (1999-12)
      Report de recerca

      This paper proposes a new representation scheme of the cerebral blood vessels. This model provides information on the semantics of the vascular structure: the topological relationships between vessels and the ...
    • Mathematical modeling of collagen turnover in biological tissue 

      Sáez Viñas, Pablo; Peña, Estefania; Martínez, Miguel Àngel; Kuhl, Ellen (2012)
      Article
      Accés obert
      We present a theoretical and computational model for collagen turnover in soft biological tissues. Driven by alterations in the mechanical environment, collagen fiber bundles may undergo important chronic changes, characterized ...
