Modeling of Mechanical behavior of Interfaces in Masonry Structures

The purpose of thisarticle,is anumerical modeling of interfaces between the brickand mortar in masonry structures, taking into account the main mechanical phenomena governing their break; such as adhesion, sliding, andthefriction. The modeling will be based on an interface coupling laws contact, friction and adhesion originally developed by the group of Michel Raous the LMA (Marseille) and implanted intheGYPTIScode.The studyis restricted toreducedcase. The comparison ofnumerical resultswith experimental resultshas been very encouraginginmost cases, and showeda goodmodel selectioninterfaceis sufficientto properly presentthe conduct ofmasonry structures.
