Abstract
A fracture toughness calibration of the Si3N4/Fe joint system has been performed for various mixed-mode loading conditions and for different thicknesses of the metal interlayer. The asymmetric four-point-bend l oading geometry was used. The values for the calibration function (Y) as well as the mode mixity (psi) of the system increase on increasing the thickness of the metal. As the loading conditions change from mode II to mode I the dependence of both parameters on metal thickness is more intensive.
