Rigid-plastic finite-element analysis of sheet-metal forming processes using a selective membrane/shell formulation
In most sheet-metal forming processes a large part of the deforming material exhibits stretch-dominant characteristics and the bending effect is found to exist only in a limited portion of the total deforming region. Thus the use of shell or continuum elements for the whole region is not economic. A selective membrane/shell (M/S) scheme is proposed which combines the layered degenerated shell e...
متن کاملA Study on the Forming of Sheet Metal Parts Using Multi-Point Forming Technology
In recent years, in order to reducing die design and manufacturing costs, Multi point forming technique has gained an increasing interest because of its high flexibility. In this process, the conventional fixed shape solid die sets are replaced with a pair of opposite matrices of controllable elements. In this paper, the fundamental principles of multi-point forming was described and the possib...
متن کاملMultiscale Friction Modeling for Sheet Metal Forming
The most often used friction model for sheet metal forming simulations is the relative simple Coulomb friction model. This paper presents a more advanced friction model for large scale forming simulations based on the surface change on the micro-scale. The surface texture of a material changes when two surfaces are in contact under a normal load. This is caused by flattening due to combined nor...

متن کاملContactless Sheet Metal Feeder for Metal-forming Machines
This paper deals with the investigation of a contactless sheet metal feeder for metal forming machines. The concept is based on an asynchronous linear motor in which the sheet metal is used as the eddy currents runner. First numerical analyses were performed by means of a parameterized finite-element (FE) model of the feeder. The focus was on the investigation of the operational characteristics...
