Nonlinear parameter identification of models for masonry

On the determination of material parameters for internal variable thermoelastic–viscoplastic constitutive models

“…Mahnken, 2002;Li et al, 2002;Morbiducci, 2003;Love and Batra, 2005;Lee et al, 2005;Bocciarelli et al, 2005;Abedrabbo et al, 2006;Ponthot and Kleidermann, 2006). The complexity of this process increases with the complexity of the material model itself.…”

Pushover Analysis for Seismic Evaluation of Masonry Wall

“…Formica et al, [15] presented a discrete mechanical model for masonry walls based on a Lagrangean description where each brick is described as a rigid body and each mortar joint as an interface element. Morbiducci [16] investigated the parameter estimation problem for brick masonry models. An identification procedure was proposed in which the uncertainties of known parameters and/or errors of measurements were main elements of distinction.…”

Damage and plasticity at the interfaces in composite materials and structures

“…For these structures and for quasi-brittle materials three main approaches based on the coupling of elastoplasticity and CDM have been proposed. The first approach, based on macro-modeling [3][4][5], considers the structure as an homogeneous anisotropic continuum. The method is suitable to describe the non-linear behavior of masonry structures [3,4] and concrete [5].…”

“…The first approach, based on macro-modeling [3][4][5], considers the structure as an homogeneous anisotropic continuum. The method is suitable to describe the non-linear behavior of masonry structures [3,4] and concrete [5]. The second approach, based on a detailed micro-modeling [3,6], takes into account the materials' and the interface's properties separately.…”
