Analysis of Optimization of Blank Holding Force In Deep Drawing By Using LS DYNA
Sheet metal forming problems are typical in nature since they involve geometry, boundary and material non-linearity. Cup drawings involves many parameters like punch and die radius, clearance, lubrication, blank holding force and its trajectories etc. So designing the tools for cup drawing involves a lot of trial and error procedure. To reduce number of costly trial error steps, the process can...
متن کاملApplication of T-shape Friction T test for Ti-6Al-4V Alloy at Elevated Temperatures
There are several parameters that have significant influence in metal forming process. One of the most important of them is friction coefficient. Friction can change the pattern of metal flow and the force needed for deformation. It is necessary to determine the friction coefficient to study the effect of friction on metal forming process. This study is concerned with numerical and experimental...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Experimental and Finite Element Studies on Formability of Low Carbon Steel Sheets using Deep Drawing
Abstract One of the commonly used metal forming processes is deep drawing, in which circular blanks are converted into a cup or shell with good surface finish. In this paper, the forming characteristics of Deep Draw Steel (DDS), a low-carbon steel with many engineering and automotive applications, is investigated by deep drawing. The forming limit diagram is a useful concept in favor of charact...
