Micro-scale continuous and discrete numerical models for nonlinear analysis of masonry shear walls

TL;DR: In this article, a damage mechanics-based continuous micro-model for the analysis of masonry-walls is presented and compared with other two well-known discrete micro-models, which discretize masonry micro-structure with nonlinear interfaces for mortar-joints, and continuum elements for units.

Multiscale computational first order homogenization of thick shells for the analysis of out-of-plane loaded masonry walls

TL;DR: In this paper, a multiscale method based on computational homogenization for the analysis of general heterogeneous thick shell structures, with special focus on periodic brick-masonry walls, is presented.

A damaging block-based model for the analysis of the cyclic behaviour of full-scale masonry structures

TL;DR: In this paper, a damaging block-based model is proposed for the numerical analysis of the cyclic behavior of full-scale masonry structures, where solid 3D finite elements governed by a plastic damage constitutive law in tension and compression are used to model the blocks, while a cohesive-frictional contact-based formulation is developed to simulate their cyclic interaction.

Finite element modelling of internal and multiple localized cracks

TL;DR: A novel tracking algorithm that can simulate cracking starting at any point of the mesh and propagating along one or two orientations is proposed, which allows the simulation of structural case-studies experiencing multiple cracking.

Strain- and stress-based continuum damage models—I. Formulation

TL;DR: In this article, a dual framework for elastic cap damage was proposed, where a strain-and a stress-based approach was employed, and a viscous regularization of strain-based, rate-independent damage models was also developed.

Plastic behavior and stretchability of sheet metals. Part I: A yield function for orthotropic sheets under plane stress conditions

TL;DR: In this article, a yield function that describes the behavior of orthortropic sheets, metals exhibiting planar anisotropy and subjected to plane stress conditions is proposed, which is shown to give a reasonable approximation to plastic potentials calculated with the Taylor/Bishop and Hill theory of polycrystalline plasticity for plane stress states.

A six-component yield function for anisotropic materials

TL;DR: In this paper, a new six-component yield surface description for orthotropic materials is developed, which has the advantage of being relatively simple mathematically and yet is consistent with yield surfaces computed with polycrystal plasticity models.

The Brittle Strength of Orthotropic Materials

TL;DR: In this article, a phenomenological fracture condition for ortho tropic brittle materials is proposed, which can account for widely differing compressive and tensile strengths in ortho tropical brittle materials.

Q1. What have the authors contributed in "A localized mapped damage model for orthotropic materials" ?

This paper presents an implicit orthotropic model based on the Continuum Damage Mechanics isotropic models. 

A major advantage lies in the possibility of adjusting an isotropic criterion to the particular behaviour of the orthotropic material. Complex orthotropic damage threshold surfaces can be built by using simpler and well-known isotropic ones, hence avoiding the complex anisotropic yield functions normally adopted in Plasticity. The model can be used for the analysis of different orthotropic materials, such as wood, fibre reinforced composites and masonry. Since the computational costs is limited, it can be used in large scale computations [ 47,68,69 ].
