Statistical behavior and misfit stresses in ceramic and metal laminated system

摘要

The statistical behavior of ceramic and metal laminates was studied, and in particular the relationship between the failure distribution of the laminate and that of the ceramic layers that it comprises. An important result of this investigation is the ability to predict the misfit stresses due to thermal processing of the laminates. A finite different scheme that was capable of calculation the local stresses at each constituent and of considering the thermal residual stresses was developed. The laminated system was constructed from 380-#mu#m-thick alumina alternating with nickel foil 25-or 50-#mu#m thick.
