| Summary: | 碩士 === 國立高雄應用科技大學 === 模具工程系碩士班 === 95 === An analysis of bimetal extrusion through a flat die, which the bimetal consisted of the Al 6061 and C1100 whose material characters are found by mean of the compress test of cylinder, is simulated by the software DEFORM 3-D in this study. The effects of the exit round of die, the extrusion ratio, the thick ratio of core and sleeve layer, the length of core and the friction factor are investigated with the extrusion load. The behavior of deformation of core can be interpreted from observing the distribution of stress and strain. The result simulated by the computer can predicted the properties of the product after extrusion process and it can be applied to extrusion process to reduce the cost and the experimental time.
