A two-dimennsional finite element analysis was perfomed to study a redistribution of residual stresses due to cutting in a ceramic/metal joint. The cutting process was simulated based on a tying function of the program where two kinds of nodes (one is the tied node and the other is a retained node) were defined at the same point on a cutting line. Release of restraint of these points means cutting. It is concluded that the residual stresses redistribute after cutting the ceramic/metal joint and the peak tensile stress occurs on the new free surface near the interface in a ceramic side. It is emphasized that the residual stress at a same point decreases after cutting, but the maximum value does not decrease.
