The physicochemical data, mechanical strength and phase composition of this
ceramic were analysed.
Also in comparison to published data for Y-TZP or common ZTA-ceramic showed that our results concerning the initial monoclinic ZrO2 are in the same range below < 2 % [4,5].
After the test the remaining static strength was 70 kN, which corresponds to a reduction of approximately 18 %.

In the present research, the effect of cyclic compressive loads of different
amplitudes on clay bricks was studied, with two main objective of acquiring specific data on the
fatigue behaviour in relation to the static behaviour and studying the fatigue effect on the possible
change of the elastic properties of the bricks.
With increasing number of cycles the load versus displacement curve shows a deterioration consisting of a reduction in its inclination relative to the displacement axis; this process comes to a limit, i.e., failure occurs, when this curve intersects the descending branch of the static test (Fig. 1b).
For a higher intensity compressive cycles, brick fatigue life can be evaluated by means of a failure criterion based on the observation of the static and cyclic curves, as already ascertained by several authors for concrete: a very good applicability was found for bricks, despite it was observed a medium variability of the data.
