Abstract: The governing equation of elastic FGM thin plates was obtained by degenerating the governing equation of viscoelastic FGM thin plates. A Levy solution of a simply supported FGM rectangular plate was gotten. Based on the Levy solution, the influence of considering and ignoring mid-plane stain, due to the inhomogeneous property of the functionally graded materials, on the static responses of the functionally graded materials thin plate is investigated.

Abstract: The governing equation of thermoelastic FGM thin plates was obtained by degenerating the governing equation of thermoviscoelastic FGM thin plates. A Navier solution of a simply supported FGM rectangular plate under thermal loads was get. Based on the Navier solution, the influence of considering and ignoring mid-plane stain, due to the inhomogeneous property of the functionally graded materials, on the maximal deflection and thermal stress of the functionally graded materials thin plate is investigated.

Abstract: A theoretical analyzing approach about a novel seismic isolation system, DFPS (Double Slipping-Surfaced Friction Plate System), is presented in this paper. Its governing equation is similar to that of the FPS friction pendulum system with single slipping surface. It is shown that the inter-storey drift resulted from seismic action could be drastically decreased on buildings equipped with DFPS system. If an optimum combination of slide radius and slipping friction coefficient is adopted, the seismic isolation effectiveness could be as high as 90%.

Abstract: Ceramics metal functionally graded materials (FGM) is applied on the dual friction pair of the green automobiles. The structure and component characteristics of FGM are better, compared with traditional Ceramics. Even with the same components, FGM bears an outstanding mechanical performance and its cracking strength, toughness and fatigue strength are relatively superior. The influence of Ceramics metal functionally graded materials on the performance of automobiles are analyzed via a comparative research and comparison of the external characteristics of automobile is made in terms of mechanism. The results indicate that the power output, fuel consumption and durability are improved considerably on the green automobiles. Improvement is also made on the wearing capability, lubricity and sealing performance as well. Hence comes the reduction of friction loss and leakage loss. The principal abrasion mechanism of FGM is plastic flowing and the secondary are brittle failure and grain abrasion.
