    Abstract: The hydrostatic bearings are broadly observed in industrial applications owing to their potential characteristics of low running friction, high load-carrying capacity, high stiffness and small viscous dissipation. Spherical bearings have advantages over other configurations of bearings because of their self-aligning property and also their capacity... Show More

    Abstract: Fracture toughness (KIC) tests have been carried out on single edge precracked beam specimens with dimensions in accordance with ISO15732 requirements for two types of zirconia and one type of alumina, i.e. ZrO2 -1, ZrO2 -2 and Al2O3. Experimental determinations of KIC for the two zirconia and one alumina materials are 12.18 MPa•m1/2, 16.35 MPa•m1/... Show More
