Deep drawing of superplastic material
Metals Technology, 1976AbstractA technique of deep drawing superplastic sheet material is described in which a differential temperature between the sheet and punch is used. With super plastic ZAM, the drawability obtained with this technique is significantly greater than that obtained with conventional materials or with superplastic materials using other techniques.

The deep drawing of thermoplastics
Polymer Engineering & Science, 1977AbstractThe theory of deep drawing, which has been developed for metals, is examined critically for thermoplastics. Two special characteristics of thermoplastics, the strong orientation hardening after initial yielding and the ease of crack formation and growth, are shown to vitiate the usual correlation between the drawability of the sheet and the low

This research work presents recent results on the formability of paper-based materials. Different kinds of commercial paperboard samples were evaluated using a laboratory 2D - formability tester, and a 3D deep-drawing equipment. It was found that the appearance of the formed shapes and the performance of paperboard in the forming process have a ...

The term metal forming refers to a group of manufacturing methods by which the given shape of a workpiece (a solid body) is converted to another shape without change in the mass or composition of the material of the workpiece. In this paper, the basics of a deep drawing process for the production of a thick plate steam boiler end caps are shown.

Deep Drawing and Stretch Forming
1976Deep-drawing and stretch-forming processes make up a considerable proportion of metal-forming operations, and have deservedly received much attention. Although they are often thought of as mutually complementary, we should remember that whereas stretch forming may well be decisive in the success or failure of a deep-drawing process as a whole, it is an

Hydrodynamic lubrication of deep drawing
An isoviscous steady hydrodynamic lubrication model for a deep drawing process is developed. Equations to calculate lubricant film thickness, radial, and drawing stresses are presented. The die inlet film thickness is related to the properties of the lubricant and the sheet metal, the tooling geometry and the operating conditions.openaire +1 more source
