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

Antonio Maria D'Altri, +4 more
- 15 Mar 2019 - 
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.

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 ].
