Cohesive surface model for fracture based on a two-scale formulation: computational implementation aspects
(Springer, 2016-10)
The paper describes the computational aspects and numerical implementation of a two-scale cohesive surface methodology developed for analyzing fracture in heterogeneous materials with complex micro-structures. This approach ...
Theoretical models to predict the mechanical behavior of thick composite tubes
(ABM, ABC, ABPol, 2012)
This paper shows theoretical models (analytical formulations) to predict the mechanical behavior of thick composite tubes and how some parameters can influence this behavior. Thus, firstly, it was developed the analytical ...
Influence of convergence angle of tooth preparation on the fracture resistance of Y-TZP-based all-ceramic restorations
(2013-03-01)
Objective: To investigate the influence of the convergence angle of tooth preparation on the fracture load of Y-TZP-based ceramic (YZ-Vita YZ) substructure (SB) veneered with a feldspathic porcelain (VM9-Vita VM9). Methods: ...

Continuum approach to material failure in strong discontinuity settings
(Elsevier Science, 2004-04)
The paper focuses the numerical modelling of material failure in a strong discontinuity setting using a continuum format. Displacement discontinuities, like fractures, cracks, slip lines, etc., are modelled in a strong ...
A two-scale failure model for heterogeneous materials: Numerical implementation based on the finite element method
(John Wiley & Sons Ltd, 2014-02)
In the first part of this contribution, a brief theoretical revision of the mechanical and variational foundations of a Failure-Oriented Multiscale Formulation devised for modeling failure in heterogeneous materials is ...
Multifield-based modeling of material failure in high performance reinforced cementitious composites
(CIMNE, 2013)
Cementitious materials such as mortar or concrete are brittle and have an inherent weakness in resisting tensile stresses. The addition of discontinuous fibers to such matrices leads to a dramatic improvement in their ...
Computational modeling of high performance steel fiber reinforced concrete using a micromorphic approach
(Springer, 2013-01)
A finite element methodology for simulating the failure of high performance fiber reinforced concrete composites (HPFRC),with arbitrarily oriented short fibers, is presented. The composite material model is based on a ...
A comparative study on finite elements for capturing strong discontinuities: E-FEM vs X-FEM
(Elsevier Science Sa, 2006-12)
A comparative study on finite elements for capturing strong discontinuities by means of elemental (E-FEM) or nodal enrichments (XFEM) is presented. Based on the same constitutive model (continuum damage) and linear elements ...
