This paper presents an analysis of the stresses in the ledge of the historic masonry model due to variations of temperature of the stone / artificial stone systems. It is clearly shown that temperature fluctuation effects can generate significant stresses in the interface layers in contact between stones and artificial stone. The thermal expansion analysis is modelled by a 3-D finite element model. In this paper is also shown complex overview of the problem of different thermal expansion of the repair and original material. The state of stress in particular geometrically different cases is confronted.
