Effective elastic and fracture properties of regular and irregular masonry from nonlinear homogenization

Seismic performance of Unbonded Fiber-Reinforced Elastomeric Isolators (UFREI) made by recycled rubber. Influence of suboptimal crosslinking

“…Such identification allows to have a numerical insight into the effectiveness of the isolation applied on a realistic case study, where the masonry superstructure is modeled with a standard Concrete Damage Plasticity material. Usually, to study the masonry in a non-linear range, more complex models of the CDP should be used that take into account the orthotropic behavior [20] [21]. However, for irregular textures, the behavior tends to be more similar to an isotropic one and the utilization of damaging/inelastic models available in commercial codes for concrete is admitted [22][23] [24].…”

Elastic Properties Estimation of Masonry Walls through the Propagation of Elastic Waves: An Experimental Investigation

“…The aim of this work is to study the use of impact tests on masonry material for the estimation of the elastic parameters by means of classic homogenization approaches for the characterization of heterogeneous media, which are based on the analysis of test windows [34][35][36][37][38][39][40][41][42]. More in detail, the novelty of this study is to investigate the effectiveness of estimating the elastic modulus of the material by analyzing the propagation velocity of the elastic waves with the increase of the structural element dimensions on which the tests are performed.…”
