Abstract: The paper presents an updated Lagrangian-type finite element procedure, formulated with reference to a surface embedded coordinated system. Membrane shell theory is employed, and an attempt is ...

Abstract: A series of warm and cold heading tests ranging from room temperature to 400 deg C have been conducted on 305 and copper bearing 302 stainless steel wires as well as 0.2 percent C steel ...

Abstract: This work provides information leading to the evaluation of the coefficient of friction for various lubricants during the first blow of a double blow heading operation on AISI 1018 steel wire. ...

Abstract: The hydraulic bulging of peripherally clamped, thin, circular disks into axisymmetric dies is studied by means of an incremental finite element method, based on membrane shell theory and formulated ...

Abstract: Plasticine, Commercially Pure Lead and 6061T6 Aluminum have been used as model materials to simulate some of the forming processes that can arise during a first blow axisymmetric heading operation ...

Abstract: The article describes a series of experiments, and some associated theoretical work, which should assist in assessing the suitability of certain steels designated for cold forging operations. The ...

Abstract: The paper deals with the effect of chamfers on the tool edge on the chip formation process. It is found that both in continuous cutting and in the exit phase of interrupted cutting where ...

Abstract: The quasi-static loading of a curved strip compressed by a flat, rigid plate is considered, with particular reference to large deformations and the ensuing buckling behavior. Experiments were ...
