Advanced numerical analyses by the Non‐Smooth Contact Dynamics method of an ancient masonry bell tower (2020, methodology): “These models were achieved through rigid blocks bounded together by points of contacts, which follow the Signorini's law, about the impenetrability condition; and the Coulomb's law, relative to dry friction.(40) Thus, this approach pointed out discontinuous nonlinear dynamics of the structures, allo”
Dynamic finite element formulation for Cosserat elastic plates (2015, background): “It is worth mentioning that, according to [67], a large number of contact points are required across the thickness of the panel in order to obtain an accurate representation of the out-of-plane behaviour with the DE model.”
A review of experimental investigations and assessment methods for masonry arch bridges (2016, unknown): “Many applications to masonry structures have been reported so far (see, amongst others: Dimitri, De Lorenzis, & Zavarise, 2011; Giamundo, Sarhosis, Lignola, Sheng, & Manfredi, 2014; Lemos, 2007; Rots, 1997; Sarhosis, Garrity, & Sheng, 2015; Sarhosis & Sheng, 2014).”
A detailed micro-modelling approach for the structural analysis of masonry assemblages (2018, methodology): “To overcome this limitation, some finite element formulations (Berto et al., 2002; Radnić et al. 2012; Milani & Taliercio 2015 & 2016) as well as other attractive tools, like the discrete element method (Sarhosis et al. 2016b; Lemos 2007; Smoljanović et al. 2013) have been developed.”
A 3D detailed micro-model for the in-plane and out-of-plane numerical analysis of masonry panels (2018, methodology): “Discrete element models (DEM) represent a further numerical strategy, utilized to analyse the mechanical behaviour of systems made of particles, blocks or multiple bodies, which appears suitable for masonry structures [33, 34, 35, 36, 37, 38, 39].”
Influence of construction method on the load bearing capacity of skew masonry arches (2018, methodology): “According to Lemos [18], the normal stiffness can have different physical interpretations even in those cases when the blocks are deformable: (a) in the case of mortared joints, the normal stiffness can be directly related to mortar thickness and its mechanical properties ; (b) For dry joints, rough”
A fast and general upper-bound limit analysis approach for out-of-plane loaded masonry walls (2017, methodology): “(DEM) [27, 28], the Non-Smooth Contact Dynamics (NSCD) method [29, 30] and combined FEM/DEM methods [31].”
