Titel
Testing of engineering ceramics under biaxial loading
Abstract
A new test procedure was developed to proof the strength of engineering ceramics under biaxial loading. This test proce- dure enables a simultaneous loading of thin-walled tubular specimen by using internal hydraulic pressure and an axial force. This leads to a wide range of biaxial stress states of combined tension/compression stresses. First test results of silicon carbide show the usefulness of the test setup. It will be used to perform comprehensive investigations of engineering ceramics. The evaluated biaxial strength beha- viour and an additional investigation of the fracture tough- ness of engineering ceramics should lead to a probabilistic modeling of ceramic failure under multiaxial loading
