    A Comparative Review of XFEM, Mixed FEM and Phase-Field Models for Quasi-brittle Cracking

    In this work, a critical comparison between three different numerical approaches for the computational modelling of quasi-brittle structural failure is presented. Among the many finite element approaches devis...

    Architecture of a multi-crack model with full closing, reopening and sliding capabilities

    This paper discusses the finite element modeling of cracking of quasi-brittle materials under cyclic loading. A damage based crack model is proposed, which considers tensile and compressive damage, irreversibl...

    Appraisement of planar, bending and twisting cracks in 3D with isotropic and orthotropic damage models

    This paper discusses the modeling of cracking in quasi-brittle materials using isotropic and orthotropic damage constitutive laws. A mixed strain/displacement finite element formulation is used, taking advanta...

    Finite element modeling of quasi-brittle cracks in 2D and 3D with enhanced strain accuracy

    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 and an isotropic damage constitutive...
