Hydroforming has become an increasingly attractive manufacturing process for the
production of hollow bodies. Numerous applications are known, especially in the automotive …

Previous studies have demonstrated that sheet formability is governed by the interlacing
effect of pure stretch forming and pure deep drawing. In this paper, knitted fabric reinforced …

The formability of sheet metals has been investigated widely in the last 5 decades. However,
formability studies on polymer composite materials are very limited and relatively new. This …

Operations for sheet metal shaping are essential to the production of many different kinds of
goods. But there is still a problem with plastic fragility in this industry, which frequently results …

From the product point of view, the onset of a visible neck during sheet metal forming sets
the limit to which a blank material can be formed. In any forming process, the blank material …

In sheet metal forming, the occurrence oflocalized necking sets the limit in which the blank
can b further formed. Previous studies have shown that sheet formability is governed by the …

Knitted fabrics are known for their excellent stretching and draping properties due to their
curved fabric architecture. In recent years knitted fabrics have been used as reinforcement …

本文採用動態顯函有限元素法, 結合材料彈塑性理論, 發展出一套增量型彈塑性大變形之三維顯
性動態有限元素分析程式, 並利用九節點元素來定義模具外形, 亦發展出彈性棒元素來處理料片 …

Recently the effects of knitted fabric reinforcement on the sheet forming of polymer sheets
have been investigated, and shown to provide strength and a more distributed strain. A new …

Previous investigations on forming of plain weft-knitted fabric composite sheets show the
ease of stretching due to fabric loop straightening. Pure dependence on stretching alone …
