On the Theories of Sheet Metal Necking and Forming Limits
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The history and the present state of the theory of sheet metal forming limits are reviewed. The theory of necking and plastic instability (Swift-Hill and Marciniak-Kuczyński models) is discussed ...
Drawing Force in Deep Drawing of Cylindrical Cup With Flat-Nosed Punch
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method for estimating the maximum drawing force in the deep drawing of cylindrical cups with flat-nosed punch is developed. The criterion is obtained using the load maximum principle for ...
