ên13th International Conferenceon Fracture June 16–21, 2013,Beijing, China -10- and using numerical model in finite elements to determine the stresses arising within the coating due to the temperature distribution over time. In step test was determined the 5,06Mpavalue as the limit of fatigue resistance of the adhesive mortar. In consequence, as the alternated stresses levels in the mortar layer does not reach this value, according to this methodology there is no risk of breakage of this layer to either case. This is due to the fact that among the materials that compose the structure, the mortar is the one with the lowest value of elasticity modulus. However, it is recommended to apply the methodology also for the other layers, especially layers of grout (subjected to large compression caused by the movement of ceramics) and ceramic (because they are subject to the higher stress levels, including bending stresses). Consequently, it is necessary to perform characterization tests for types of grout, besides testing flexural behavior for ceramic pieces. References ANSYS.Analysis System.
