立鋁合金A6061-O 與 A6061-T6 之材料模型,包括 Hill48 與 Barlat91 等降伏準則搭配 Yoshida 硬化準則。使用求得之材料模型進行 V 型彎 曲與 U 型帽狀引伸之模擬,並且搭配相對應之成形實驗進行模擬驗 證,進而探討最適合鋁合金A6061-O 與 A6061-T6 之材料模型。以 V 型彎曲而言,各材料模型預測之回彈量皆與實驗達到準確預測。而以 U 型帽狀引伸而言,則是以考慮到包辛格效應之 Yoshida 模型搭配
Hill48 或 Barlat91 兩材料模型對於預測 A6061-T6 側壁捲曲有著較準 確的預測。後續本論文使用Barlat91 搭配 Yoshida 模型進行探討鋁合 金 A6061-T6 之回彈改善方法。使用姚順偉[29]的阻料條設計流程探 討屬於鋁合金A6061-T6 之阻料條設計,先探討合適的變壓料力範圍,
