“…In the developed two-dimensional mesoscopic masonry model, the GFEM technique is used so that the behaviour of each brick is governed by a designated set of enhanced degrees of freedom [12]. Consequently, the displacement field can be decomposed according to…”

“…the bricks and joints, to one orthotropic material whereas the latter approach models the constituents as separate entities. In this contribution, two mesoscopic masonry models are presented and compared: a model in which the joints are represented as strong discontinuities [2] and a model in which weak discontinuities are used to model the joints [11].…”

“…Unlike classical models, where the strong and weak discontinuities are modelled, respectively, by interface [1] and continuum elements [6], the discontinuities are incorporated using the Generalised Finite Element Method [10,12], whose formulation is described in Section 2. This method allows an in-element embedment of the discontinuities, i.e.…”

“…In this contribution we propose an compare two modelling approaches in both categories: (i) a discontinuous model based on the generalised finite element method (Vandoren et al 2013a) and (ii) a novel continuous finite element model based on the implicit gradient enhanced damage model. Both approaches require additional degrees of freedom which describe the jump fields of the discrete cracks and a regularising non-local strain field, respectively.…”

In this contribution we propose and compare two finite element models for modelling damage in masonry structures. The first model belongs to the class of discontinuous models, in which masonry failure is modelled through the insertion of discrete displacement jumps at the mortar joints. Discontinuities are incorporated using the Generalised Finite Element Method (GFEM), allowing for an on-the-fly introduction of cracks. The second model is a novel continuous model, in which masonry damage is smeared out over a finite volume. Mesh-sensitivity of strain localisation in this model is regularised by means of a gradient enhanced damage model which takes into account the anisotropy of masonry.

Predicting the structural response of masonry structures with acceptable accuracy is paramount to safeguard the historical heritage and build new constructions with safety margins adequate to modern standards. However, due to the heterogeneous nature and anisotropic response of masonry, such prediction is still difficult to achieve, where most current masonry representations are based upon homogeneous isotropic material models or even more simplified masonry macro-elements. In this article, a novel anisotropic constitutive model to be used in detailed 3D continuum FE representations is described. This is based upon the application of the transformed-tensor method to an isotropic uncoupled plastic-damage model, which is further enhanced by additional novel features enabling the proper definition of the shear behavior both in terms of yielding surface and damage evolution while increasing local computational robustness. Illustrative examples at different scales are presented, highlighting the characteristics and potential of the developed masonry material model. Focus is placed on the mechanical behavior under uniaxial and biaxial stress states considering pure compression on wallets with varying inclination of the material principal axes and the out-of-plane response of wall components.The numerical results confirm the ability of the proposed constitutive model to predict typical masonry anisotropic response characteristics, which cannot be accurately represented by standard isotropic representations commonly used in professional practice and research.
