Reliability prediction and design of multi-layered structure necessitates the knowledge of the mechanical proper-ties of the individual layers, in particular fracture toughness. To measure fracture toughness of typical anode, composed of 60 wt.% NiO and 40 wt.% 3YSZ (60:40 Ni-YSZ) used in Solid Oxide Fuel Cell (SOFC). controlled buckling test was used. A simple set-up was made where a compressive strain was applied on a thin substrate supporting the anode. Both curvature and film strength are calculated from the applied strain, elastic modulus and geometric dimension of the sample. The fracture toughness is calculated to be 5 +/- 0.28 MPa root m.
