On one hand lightweight sheet materials are characterized by high specific strength but on the other hand, they are limited in the design of sheet metal products. To extend the range of producible geometries, special forming processes at elevated temperatures have been developed. For describing ...
From zonal flow to convection rolls in Rayleigh-B\\'enard convection with free-slip plates Rayleigh-B茅nard (RB) convection with free-slip plates and horizontally periodic boundary conditions is investigated using direct numerical simulations. Tw... Q Wang,KL Chong,RJAM Stevens,... 被引量: ...
5.1. Sheet forming turns the flat metal disk at the left into a three-dimensional structure by plastic deformation. Although sheet forming works with thermoset materials (Gutowski et al., 1995) there is more interest in forming thermoplastic matrix composites in sheets. For one thing, sheet formi...

32 MECHANICAL PRESSES / THE WHOLE WORLD OF SHEET METAL FORMING DIE LIFE SPANS AND COMPONENT QUALITY The die life span can be significantly increased by optimally adjusting the forming speed in the critical process range. In addition, it is possible to reduce the influence that fluctuating coil ...
processand sheet metal processing. The main difference between these two types of forming methods is the different surface area to volume ratio. The surface area of the workpiece formed by the bulk deformation is low. Metals processed using sheet metal have a higher surface area to volume ratio...
