On representation of macroscopic crack in periodic fine-scale discrete mechanical models
Jan Raisinger, Jan Eliáš
In multiscale modeling of heterogeneous softening materials, boundary conditions (BC) in the fine-scale model strongly influence the strain localization pattern and the macroscopic…

Simulating Heterogeneity within Elastic and Inelastic Discrete Mechanical Models
Jan Raisinger, Qiwei Zhang, John E. Bolander +1
Two approaches to incorporate heterogeneity in discrete models are compared. In the first, standard approach, the heterogeneity is dictated by geometrical structure of the discrete…
