Nonlinear transient thermoelastic analysis of functionally graded ceramic-metal plates. (English) Zbl 0930.74037

Summary: The response of functionally graded ceramic-metal plates is investigated using a plate finite element that accounts for transverse shear strains, rotary inertia and moderately large rotations in the von Kármán sense. We study the static and dynamic response of the functionally graded material (fgm) plates by varying the volume fraction of ceramic and metallic constituents using a simple power law distribution. Numerical results for the deflection and stresses are presented, and the effect of the imposed temperature field on the response of the fgm plates is discussed. It is found that, in general, the response of the plates with material properties between those of the ceramic and metal is not intermediate to the responses of the ceramic and metal plates.
