This Master Thesis presents static and dynamic material tests conducted for different types of bricks and numerical simulations developed to model static tensile and compression tests conducted at the University of the Bundeswehr. Based on the results of the experimental investigations, a new material model for masonry bricks was developed. This model was implemented with a user subroutine developed in ANSYS AUTODYN. These material models, which are suitable for a detailed micro-model approach, consider the dynamic increase of the material strength and the degradation of the material properties due to fracture and material damage. In this Master Thesis, the analysis of the experimental investigations, the material model developed for bricks and its verification and validation for static tensile and compressive tests are presented.
