Figure 6 –SX stresses in section BB’ after thermal shock, ceramicsclear and dark Regarding the SY stresses, due to the compressive stress in the x direction, the sections AA’ and CC’ there were tensile stresses in the sense tendency to detachment between layers of the structure. The highest stress values were observed in these layers beneath the layer of plaster, where was restrictionof no movement. Moreover, layers of plaster and adhesive mortar section BB’ worked with SY compression stresses, and the main reason is because the ceramic parts are compressing the grout in the x direction. In response, crushed grout spreads up and down in the vertical direction, compressing both the adhesive mortar as the plaster situated below it. Figure 7 – SY stresses in section BB’ after thermal shock, ceramicsclear and dark. TheSXY shear stresses encountered to the coating structure in both models were very low compared to the stresses SX and SY. In section CC’ the values were effectively zero, due to the central position of this section. The reason for the low values of SXY is because of the deformations within the structure are of thermal nature, which normally do not produce shear stresses. As a result, the values should be more restrictions on movement imposed on the structure than the thermal loading
