Micromechanical modeling of brick-masonry fracture

This paper presents a micromechanical model for the analysis of mode I fracture of brick masonry. The analysis is based on a detailed modeling of brick and mortar fracture by means of the fictitious (or cohesive) crack model. Fracture properties for brick and mortar are first independently determined by specific tests and then are input to a numerical model in which bricks and mortar joints are treated separately. The composite fracture model obtained in this way can accurately predict the fracture of masonry panels.
