A continuous-discontinuous model for crack branching
(John Wiley & sons, 2019-10-05)
Article
Accés obertA new continuous-discontinuous model for fracture that accounts for crack branching in a natural manner is presented. It combines a gradient-enhanced damage model based on nonlocal displacements to describe diffuse cracks ... -
A crack-tracking technique for localized cohesive-frictional damage
(2015-12-01)
Article
Accés obertThis paper extends the use of crack-tracking techniques within the smeared crack approach for the numerical simulation of cohesive-frictional damage on quasi-brittle materials. The mechanical behaviour is described by an ... -
An optimization-based phase-field method for continuous-discontinuous crack propagation
(John Wiley & sons, 2018-10-05)
Article
Accés obertA new continuous-discontinuous strategy for the computational modeling of crack propagation within the context of phase-field models of fracture is presented. The method is designed to introduce and update a sharp crack ... -
eXtended hybridizable discontinuous Galerkin for incompressible flow problems with unfitted meshes and interfaces
(John Wiley & sons, 2019-02-17)
Article
Accés obertThe eXtended hybridizable discontinuous Galerkin (X-HDG) method is developed for the solution of Stokes problems with void or material interfaces. X-HDG is a novel method that combines the hybridizable discontinuous Galerkin ... -
Extended hybridizable discontinuous galerkin with heaviside enrichment for heat bimaterial problems
(2017-01-28)
Article
Accés obertA novel strategy for the hybridizable discontinuous Galerkin (HDG) solution of heat bimaterial problems is proposed. It is based on eXtended finite element philosophy, together with a level set description of interfaces. ... -
Étude de la stabilité d'une formulation incompressible traitée par X-FEM
(2006-06)
Article
Accés obertThe treatment of (near-)incompressibility is a major concern for the simulation of rubber-like parts, or forming processes. The use of mixed finite element methods is known to prevent the locking of the F.E. approximation ... -
Numerical model for the endocytosis of nanoparticles
(Universitat Politècnica de Catalunya, 2013-01-18)
Tesina
Accés obertThe endocytosis is the process used by cells to uptake selected external particles such as viruses, drugs or microorganisms among others. The receptor mediated endocytosis is one of the most effective methods to capture ...
