Fast brick-based homogenized limit analysis for in- and out-of-plane loaded periodic masonry panels

Simone Tiberti, +1 more
- 15 Apr 2020 - 
TL;DR: In this paper, a 3D brick-based model is presented for the derivation of in-and out-of-plane homogenized failure surfaces for masonry elements, where the considered masonry panel is discretized into regular parallelepiped 3D finite elements that are supposed to be rigid.

Wei He, +4 more

An anisotropic damage formulation for composite materials based on a gradient-enhanced approach: Formulation and implementation at small strain

Bo Yin, +4 more
- 01 Oct 2020 - 
TL;DR: In this paper, the authors describe an anisotropic damage evolution by incorporating a gradient enhanced model for composite materials and introduce three independent non-local variables, which subsequently lead to independent degradation of the components in material stress and the consistent tangent.

Multiscale multiphysics simulation in composite materials

Stefano Zaghi
TL;DR: The focus of this work is the numerical modeling of the microscale behavior of inhomogeneous materials, with special attention to composite materials under thermo-mechanical loading conditions, and a critical comparison of the proposed continuous micro-model with other two well-known discrete micro-modeling strategies.

A total‐strain based orthotropic continuum model for the cyclic nonlinear behavior of unreinforced brick masonry structures

Marianthi Sousamli, +2 more
- 03 Jan 2022 - 
TL;DR: In this article , a total-strain based rotating crack approach is proposed to analyze the cyclic, nonlinear behavior of brick masonry structures, which describes tensile and compressive failure in the rotating principal directions, while including indirectly shear failure through an internal iterative algorithm.

A General Theory of Strength for Anisotropic Materials

Stephen W. Tsai, +1 more
- 01 Jan 1971 - 
TL;DR: In this article, an operationally simple strength criterion for anisotropic materials is developed from a scalar function of two strength tensors, which satisfies the invariant requirements of coordinate transforma tion, takes into account the difference in strengths due to positive and negative stresses, and can be specialized to account for different material symmetries, multi-dimensional space, and multi-axial stresses.

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 ].
