A mixed micromechanical homogenisation scheme for the prediction of the 3D orthotropic elastic properties of different masonry bond typologies
(Elsevier, 2023)
Article
Open AccessMasonry structures composed of two distinct material phases (units and mortar) with potentially vastly different elastic properties are characterised by strong orthotropy. The variety of commonly employed bond typologies ... -
Advanced processing of remotely sensed big data for cultural heritage conservation
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Open AccessDamage assessment, protection and preservation of built patrimony are a priority at national and local levels due to their importance to many cultural and economic aspects. This paper presents a methodology to estimate the ... -
An innovative image processing-based framework for the numerical modelling of cracked masonry structures
(Elsevier, 2021-05)
Article
Open AccessA vital aspect when modelling the mechanical behaviour of existing masonry structures is the accuracy in which the geometry of the real structure is transferred in the numerical model. Commonly, the geometry of masonry is ... -
