Time-dependent springback of advanced high strength steels
, 2018 Aluminum alloys are known to undergo time-dependent springback following forming while typical autobody steels of the 1990s do not. This behavior has been attributed to larger residual stresses relative to the yield stress in aluminum and to faster creep

A Study of Springback in the Sheet Metal Forming of Advanced High Strength Steel
, 2007 為了減少溫室氣體的排放，並提昇燃油效率，汽車減重為各大汽車廠努力的目標，而為達到此目標，各大車廠紛紛採用高強度鋼板來取代傳統鋼板，因為高強度鋼板相較於傳統鋼板具有高強度之特性，能夠藉由減少汽車板金件板厚來達到減重的目的。然而在沖壓成形中，回彈為無法避免的問題，且隨著使用之材料的強度愈高，回彈現象愈嚴重，故本研究採用V型彎曲、U型彎曲以及U形帽狀（U-hat）成形實驗來了解回彈之特性，並選用270級軟鋼、590R、590Y高強度鋼板來了解高強度鋼板與傳統鋼板在回彈現象的差異性。在製程參數上探討沖頭圓角 ...

EFFECT OF SPRINGBACK IN DP980 ADVANCED HIGH STRENGTH STEEL ON PRODUCT PRECISION IN BENDING PROCESS
Acta Metallurgica Slovaca, 2019 Springback is a common phenomenon in sheet metal forming, in which the material undergoes an elastic recovery as applied loads are removed. Springback causes the forming shape to deviate from the intended design geometry.
