英文摘要	This paper presents a method for analyzing some product properties of functionally graded magneto-electro-thermoelastic (METE) multilayer composites. The method is based on an exact matrix formulation for the effective properties of multilayer composites with various coupled physical effects including piezoelectricity, piezomagnetism, and thermoelasticity. Analytical expressions are derived for the effective properties of a functionally graded transversely isotropic METE multilayer composite. The effects of functional gradation on the pyroelectric and pyromagnetic coefficients are numerically evaluated. It is shown that both the pyroelectric and pyromagnetic coefficients can be significantly enhanced (more than two times) by functional gradation, and the relative volume fractions at which these coefficients are maximized tend to extreme values. It is thus demonstrated that the present method can be used in the design of multilayered METE composites for the purpose of achieving a maximum energy conversion or transduction capability.; Mechanics; SCI(E); EI; 0; ARTICLE; 4; 849-860; 223
