The design of multi stage deep drawing processes requires the evaluation of many process parameters such as the intermediate die geometry, the blank shape, the sheet thickness, the blank holder force, friction, lubrication etc..These process parameters have to be determined for the optimum forming conditions before the process design. In general sheet metal forming may involve stretching drawin...

Metal coating, metal materials are of two or more layers. The coating metals are widely used in industry. These sheets or saving performance and cost effective solution or both the user. Performance coating metals according to usage in structural applications, settings thermal expansion of the thermo-mechanical control (thermostat), electrical, magnetic, corrosion resistant, flowering and decor...

The issue of pressure sensitivity of anisotropic sheet metals is investigated with introducing two new non-AFR criteria which are called here linear and non-Linear pressure sensitive criteria. The yield and plastic potential functions of these criteria are calibrated with directional tensile/compressive yield stresses and directional tensile Lankford coefficients, respectively. To determine unk...

plastic instability which results in the localization and failure of sheet metals has been studied in equibiaxial stretching of commercial purity aluminium sheet. attention was focussed on two main industrial conditions of the material. these were representative of the materials that could be processed by the commercial batchannealing process (slow heating, long time) or by a continuous anneali...

separation approaches affect organic contaminant levels. Thus, this fact sheet will focus primarily on heavy metal contaminants. Those metals of greatest concern in compost—cadmium, mercury, and lead—can be harmful to animals and humans at relatively low concentrations and tend to accumulate in soil, plants, and animals. For most of these potentially harmful metals, the levels in MSW composts a...

This paper studied the deformation mechanisms of sheet metals stamped by rigid punches and deformable dies. Emphasis was placed on the development of elastic plastic zones in the sheet workpieces, on the functions of the die parameters and on their correlations with spring-back. It was found that the reduction of spring-back was due mainly to the interface interaction offered by the dies. The p...
