It is well-known that large thermal stresses are caused in a ceramic-to-metal joint by thermal expansion mismatch. Barton's analysis for stresses in cylindrical rods was reformulated in terms of stresses arising from thermal expansion mismatches in elastically homogeneous cylindrical joints, and qualitative agreement was shown between these results and those produced by finite element calculations. Here, the authors apply these results to homogeneous joints with interlayers having different thermal expansion coefficients, to examine the effect of interlayer thickness on diminishing thermal expansion mismatch stress.
