    J. of Heat Transfer (2018). (preprint) Vol. 140 (8), pp. 12

    Abstract
    In this work, a novel phenomenological model is proposed to study the liquid-to-solid phase change of eutectic and hypoeutectic alloy compositions. The objective is to enhance [...]

  • Journal of Non-Newtonian Fluid Mechanics (2016). (preprint) Vol. 228, pp. 1-16

    Abstract
    This paper presents the application of a stabilized mixed pressure/velocity finite element formulation to the solution of viscoplastic non-Newtonian flows. Both Bingham and [...]

    Computational Mechanics (2016). (Preprint) Vol. 58 (3), pp. 511–532

    Abstract
    This paper presents an explicit mixed finite element formulation to address compressible and quasi-incompressible problems in elasticity and plasticity. This implies that [...]

    Computational Mechanics (2017). (preprint) Vol. 60 (5), pp. 767–796

    Abstract
    This paper discusses the finite element modeling of cracking in quasi-brittle materials. The problem is addressed via a mixed strain/displacement finite element formulation [...]

    Abstract
    A hierarchically preconditioned conjugate gradient (PCG) method for finite element analysis is presented. Its use is demonstrated for the difficult problem of the non‐linear [...]

    Computational Mechanics (2015). (preprint) Vol. 55 (3), pp. 543-559

    Abstract
    Low-order finite elements face inherent limitations related to their poor convergence properties. Such difficulties typically manifest as mesh-dependent or excessively stiff [...]

    Int. J. Solids and Structures (2015). (preprint) Vol. 71 (1), pp. 19-38

    Abstract
    Once strain localization occurs in softening solids, inelastic loading behavior is restricted within a narrow band while the bulk unloads elastically. Accordingly, localized [...]

    Engineering Fracture Mechanics (2015). (preprint) Vol. 150, pp. 96-114

    Abstract
    This paper extends the use of crack-tracking techniques within the smeared crack approach for the numerical simulation of cohesive–frictional damage on quasi-brittle [...]

    Int. J. Solids and Structures (2017). (preprint) Vol. 135, pp. 148–171

    Abstract
    In the present paper, a new d+/d− damage model apt for quasi-brittle materials is described and its validation is carried out considering unreinforced [...]

    Abstract
    Pin geometry is a fundamental consideration in friction stir welding (FSW). It influences the thermal behaviour, material flow and forces during the weld and [...]

    Engineering Fracture Mechanics (2017). (preprint) Vol. 176, pp. 235–256

    Abstract
    The testing of mode III and mixed mode failure is every so often encountered in the dedicated literature of mechanical characterization of brittle and quasi-brittle [...]

  • Int. J. Numer. Meth. Engng. (2008). Vol. 76 (12), pp. 1930-1954

    Abstract
    Traditional smeared orthotropic models display an unacceptable dependence of the solution on the alignment of the mesh, which usually manifests as stress locking. A solution [...]

    International Journal of Plasticity (1999). Vol. 15 (3), pp. 319-351

    Abstract
    The paper presents the Strong Discontinuity Approach for the analysis and simulation of strong discontinuities in solids using continuum plasticity models. Kinematics [...]
