[Using moiré interferometre in the study of porcelain-fused-metal interfacial fracture mechanics].

Objective: To evaluate the usage of moiré interferometre in porcelain-fused-metal interfacial fracture mechanics.

Methods: Raster was produced on the surface of samples with different thickness of porcelain and metal in 5 groups. The stripes of u field and v field under different load were collected.
