In order to ensure the structural safety of such buildings and to plan appropriate interventions, it is important to understand the failure mechanism and to estimate well the force and deformation capacity. Simulation techniques for masonry are commonly divided into three categories: the macro-modeling method, the simplified micro-modeling approach, and the detailed micro-modeling approach. Most previous research, especially for stone masonry, was based on the macro-modeling approach and the simplified micromodeling approach. The detailed micro-modeling approach was not applied because of various experimental and numerical difficulties. However, without modelling the mortar explicitly, the effect of shape and size of stones and stone pattern cannot be reflected explicitly. This paper contributes to the numerical investigation of stone masonry structures on the detailed-micro level. The damage within the mortar are simulated by a continuum damage-plasticity model while the damage of the interface are simulated by dynamic insertion of cohesive elements. The model is implemented in the open source software Akantu developed at EPFL, Switzerland.
