A New Technique for Fracture Characterization of Ceramics at Room and at High Temperature

CODEN: JTEVAB

Abstract

A new technique for performing stable tests in ceramic materials is analyzed in depth. The new feature consists in using an analog output of a laser metrology apparatus that measured the crack mouth opening displacement (CMOD), as the feedback signal to control a servohydraulic testing machine. In this study, we go deeply into the analysis of the experimental parameters that control the performance of this technique. Finally, the temperature dependence is shown for the fracture parameters obtained from stable tests of single-edge-pre-cracked-beam specimens (SEPB) of 3 mol% Y-TZP.
