Popis:	The thermal expansion behavior and residual stresses in multilayer capacitor (MLC) systems are analyzed in the present study. An MLC consists of a laminate of multiple alternating electrode layers and dielectric layers sandwiched between two ceramic cover layers. An analytical model is developed to derive simple closed-form solutions for the apparent coefficients of thermal expansion (CTEs) of the laminate. Plasticity of electrodes is included in the analysis. The predicted apparent CTEs are compared with measurements of some laminated ceramic composites. The effects of plasticity on apparent CTEs and residual stresses in MLC systems are discussed.
