Abstract
A new technique that provides stable fracture tests in brittle ceramic materials at room and at high temperature is presented. This techniqu e uses the crack mouth opening displacement signal from a laser extens ometer to feed the servo control of a hydraulic testing machine. In th is way it is possible to obtain-in addition to the fracture toughness- the fracture energy and the R-curve, in a single test.
