Investigation on the Curvature and Stress Distribution of Laminates Based on an Analytic Solution and FE Simulation.

The potential combinations of favorable properties give metal-ceramic laminates (MCLs) a high degree of application flexibility. However, the different thermal expansion coefficients (CTEs) and shrinkage rates of the metals and ceramics during the co-sintering process often lead to large internal stresses that cause undesired deformation or even production failures. In practice, the identification of manufacturable MCLs relies on the "trial and error" principle, which usually requires a long development period.
