Numerical analysis of fracture behaviour of multilayered bimaterials composites beams

In the present work the finite element method is used to calculate the energy release rate at the interfacial crack tip of Al 2O 3/ZrO 2/Al 2O 3 and Al 2O 3/metal/ZrO 2 composite. The behaviour of the bonded materials is supposed to be linear and elastic. The effects of the layer number, the thickne...

Zusammenfassung:	In the present work the finite element method is used to calculate the energy release rate at the interfacial crack tip of Al 2O 3/ZrO 2/Al 2O 3 and Al 2O 3/metal/ZrO 2 composite. The behaviour of the bonded materials is supposed to be linear and elastic. The effects of the layer number, the thickness of the composite beam, the crack length as well as of the crack position on the variation of the energy release rate at the crack tip were highlighted.
