Title
The concentric-ring-test and its application for determining the surface strength of ceramics
Other Title
Der Doppelringtest und seine Anwendung für die Ermittlung der Oberflächenfestigkeiten von Keramiken
Abstract
The concentric-ring-test is utilized to determine the strength of high-density aluminas for biomedical use. A suitable experimental arrangement is presented which leads to a region of constant biaxial stress. The applicability for distinguishing sensitively between various surface preparations is demonstrated. In this sense, this test appears to be advantageous compared with uniaxial bending tests.
