Abstract: Masonry represents one of the most important construction materials used for buildings worldwide. The lately highly increased number of terrorist attacks using explosives on buildings requires knowledge on the behavior of masonry under blast waves. The paper presents the types of models used for masonry and the material constitutive models which can be used for the brick and the mortar. Modeling at a micro level and the material model Johnson-Holmquist-Cook were chosen for accurately obtaining the behavior of the two components of masonry under the explosive action. For the validation of the chosen model experimental tests with explosive plastic charges placed on bricks or in the joint between the bricks were conducted. Based on these validations numerical simulations were then performed for the determination of the behavior of masonry walls at explosive actions.

Keywords: brick, mortar, detonation, Johnson-Holmquist-Cook constitutive model
