The isothermal forging of a titanium alloy engine disk is analyzed by the rigid-viscoplastic finite element method. Deformation mechanics of the forging process are discussed, based on the solution. The effects of temperature and heat conduction on the forging process are also investigated by coupled thermo-viscoplastic analysis. Since the dual microstructure / property titanium disk can be obtained by controlling strain distribution during forging, the process modeling by the finite element method is especially attractive.

A fully automatic forging simulation technique in hot-former forging is presented in this paper. A rigid-thermoviscoplastic finite element method is employed together with automatic simulation techniques. A realistic analysis model of the hot-former forging processes is given with emphasis on thermal analysis and simulation automation. The whole processes including forming, dwelling, ejecting, and transferring are considered in the analysis model and various cooling conditions are embedded in the analysis model. The approach is applied to a sequence of three-stage hot former forging process. Nonisothermal analysis results are compared with isothermal ones and the effect of heat transfer on predicted metal flows is discussed.

Element Method

The use of numerical simulations has been widespread in many engineering fields and related areas. One of the main numerical methods used in modeling and simulations is the finite element method (FEM). Despite its wide dissemination, especially in mechanical and civil engineering, FEM has high potential to be applied in other areas, such as in agricultural engineering. This paper aims to present a review of the FEM applications in three agricultural engineering areas. This research is focused on agricultural mechanization, agricultural product processing and soil mechanics, since these are agricultural engineering areas with highest number of publications using FEM. As result, it is expected greater FEM dissemination in other agricultural engineering areas. In addition, modeling and simulation techniques can be widely used in order to represent the increasing behavior of agricultural machinery and products from real physical systems.
