摘要: 
本文主要研究輕薄短小且多功能特性的金屬複合材料的沖剪特性。針對銅C11000及鋁A1050二母材疊合而成的疊層金屬複合材料,建立其有限元素模型,並以有限元素軟體DEFORM模擬不同體積比率的複合板材沖剪過程,得到不同體積比率於沖頭行程的影響,最後以不同體積比率的金屬複合板材進行沖剪成形實驗加以討論並驗證有限元素模擬的結果。

研究結果顯示,不同體積比率的複合板材依其比例不同,所得到的沖頭負荷及板材斷面皆不相同。不同的板厚進行模擬,初始斷裂並不會隨板厚改變而改變,唯有沖頭負荷會隨著板厚改變而改變。由實驗結果可知,不同體積比率的板材斷面,以鋁材在上或是銅材在上進行沖剪實驗,發現相同板材其斷面的擠壓面會因銅材在上或鋁材在上不同而使斷面不同,板材斷面以鋁材在上的擠壓面較銅材在上的擠壓面明顯許多。

This study is aimed to investigate the blanking characteristics of clad sheet metals, which is a material with thin, light weight, and multi-function properties. In this study, the blanking process of clad sheet metals composed of copper C11000 and aluminum A1050 with diverse volume fractions was simulated by using commercial finite element software DEFORM to obtain the effect on punch stroke due to diverse volume fractions. Blanking experiments for clad sheet metals with diverse volume fractions are also performed to verify the simulation results.
The results show that punch load and cross-section of clad metal varies with the ratio of volume fractions of the clad sheet metal. The simulation results show that initial fracture does not change for different thickness, but the punch load is changed due to different thickness. The blanking experiments on the clad sheet metal with A1050 on top and C11000 on top with same volume fractions show that the extruded surfaces of cross-section are different. The extruded surface of the cross-section for aluminum on the top is clearer than the copper on the top.
