本研究建立一金屬成形加工的三維有限元素分析理論模式與電腦程式可以模擬金屬成形加工的模擬處理，在本研究中先建立一熱傳遞有限元素模式和一個三維大變形熱彈塑有限元素模式，然後再將此二個模式結合形成一個新的完全理論模式。在這新的理論模式中是包括熱傳遞的一個三維大變形熱彈塑有限元素模式，可用於 金屬成形加工的一個三維數值製程模擬分析。在這個理論模式中，元素變形和溫度變異的二變數安置在同一個含雙變數的擴充矩陣；也就是說熱彈塑剛性矩陣和熱傳遞剛性矩陣安置在同一個擴充剛性矩陣。在最後將本研究建立的數值分析模式用於模擬鋁板輾壓製程加工，以證明本研究建立的三維有限元素分析理論模式與電腦程式為可行。

We have developed a finite element model that is to establish a heat transfer finite element model and a three dimensional large deformation thermal-elastic-plastic finite element model, which is then coupled to form a complete theoretical model including heat transfer. A three dimensional numerical simulation model of metal rolling formation is developed from the theoretical model. In this theoretical model, the two variables of element deformation and temperature variation are placed in a variable matrix. The thermal elastic plastic rigid matrix and heat transfer rigid matrix are placed in the same expansion rigid matrix. The numerical simulation analytical model developed in this paper was used to simulate aluminum strip rolling. Simulation of the rolling process of aluminum strips in cold rolling and hot rolling under different reductions of the strip were conducted to obtain the effects of different reductions of the strip on rolling.
