FEM analysis of orthotropic masonry walls via localized damage models

摘要: In finite element analysis of masonry structures, continuum damage models are generally combined with a smeared description damage. This common approach however, fails to provide realistic simulation and only affords general information on expected levels. Moreover, spurious mesh-size mesh-bias dependence emerges from the discrete problem. order overcome these drawbacks, this work proposes model modified in such way that it can reproduce localized individual (discrete) cracks. is achieved by means crack tracking algorithm, which enforces develop along single row elements. addition, material orthotropic behaviour simulated making use concept mapped stress strain tensors anisotropic real space scaled isotropic one. original methodology establishes one-to-one mapping relationship between and that corresponding way, problem solved results back onto field, consequent advantages computational point view. The validity demonstrated through comparison between numerical experimental evidence observed an in-plane loaded wall.
