Building on the results of a previous work (Cuomo et al. in J Elast, 2024), using the asymptotic homogenisation theory of discrete periodic truss networks in large deformations, we extend the analysis to systems whose elements present a complex rheological behaviour, that includes damage (Mullins effect), softening due to damage and a phenomenological model of buckling. Applications to periodic networks subjected to uniaxial tensile and simple shear tests are presented, examining the influence of the internal topology of the network and of the properties of the constituents.

摘要

Building on the results of a previous work (Cuomo et al. in J Elast, 2024), using the asymptotic homogenisation theory of discrete periodic truss networks in large deformations, we extend the analysis to systems whose elements present a complex rheological behaviour, that includes damage (Mullins effect), softening due to damage and a phenomenological model of buckling. Applications to periodic networks subjected to uniaxial tensile and simple shear tests are presented, examining the influence of the internal topology of the network and of the properties of the constituents.
