In this work, cold bulge forming of an Aluminium-Magnesium (Al-Mg) sheet with a solid bulging medium is performed experimentally and numerically.  Mechanical properties and thickness variations of Al-Mg sheet are evaluated before and after the forming process.  The results indicated that the Al-Mg sheet has taken the desired shape without necking using the cold bulge forming process.  Also, the...

In Incremental sheet metal forming process, one important step is to produce tool path, an accurate path of the main challenge incremental process. Various factors should be considered prior generation i.e. mechanical properties metal, holding mechanism, speed, feed rate and size. this work investigation studies have been carried out find different strategies control twist effect in final produ...

Incremental sheet forming (ISF) technology is a suitable and flexible solution to create complex 3D geometries of the sheet. A gradually formed into desired shape with tool usually attached CNC machine or robot. This process valid metal as well polymer sheets. However, inaccuracy geometry occurring errors in previously discussed industries prove novelty technology.
 In this research novel ...

In most of the sheet forming processes, production of the parts with minimum thickness variation and low required force is important. In this research, minimization of the sheet thinning and forming force in the hydraulic deep drawing process has been studied. Firstly, the process is simulated using the finite element method (FEM) and simulation model is verified using the experimental results....

Using computer simulations of an atomistic glass-forming liquid, we investigate the fluctuations of the overlap between a fluid configuration and a quenched reference system. We find that large fluctuations of the overlap develop as temperature decreases, consistent with the existence of the random critical point that is predicted by effective field theories. We discuss the scaling of fluctuati...
