The design of repair mortars for renovation of historic objects depends on many aspects. One of these aspects is the impact of the difference of thermal expansion coefficient between mortar and stone. This paper is focused on thermal stress close to the corners of the stones. Three 3-D detail finite element models of masonry which have different radius of curvature in the corners of stone were used for computation of thermal stress. The main result is that shape of stones in ashlar masonry significantly affects the values of thermal stress. The higher radius of curvature of the stones in corners causes significant decrease of thermal stress values in the corners of stone.
