The study does not capture the post-peak behaviour of the analyzed specimens using force-controlled simulations.

    Exploring the application of rigid triangular blocks in simulating the mechanics of masonry composites via DEM · 2026 · DOI

  • The present study has several limitations. Material properties were adopted from literature sources because in-situ and laboratory tests could not be performed on the registered historical structure. In addition, the numerical model was developed using a macro-modeling approach, and explicit soil– structure interaction effects were not considered.
