Full Article:

This paper presents static and dynamic material tests conducted for different types of bricks. Based on the results of these experimental investigations, a new material model for masonry bricks has been developed. This material model, which is suitable for a detailed micro-model approach, considers the dynamic increase of the material strength and the degradation of the material properties due to fracture and material damage. During this project a material model for mortar has been developed also, but it will not be shown here because of lack of space. The material models for the bricks and the mortar have been implemented in ANSYS AUTODYN and can be used to examine the complex material and structural behavior of mansory walls under dynamic loadings (e.g. explosions, earthquakes). In this paper, the material model develped for bricks and its validation for static tensile and compression tests will be presented.
