The purpose of this manuscript is to carry out an experimental and numerical investigation of bulging process of aluminum AA1050-H14 sheet metal in free expansion when using a flexible punch. Hole flanging is a metal forming process that creates a raised edge or collar around a pre-existing hole in a sheet metal workpiece. This technique utilizes specialized tooling to deform the material surrounding the hole, typically resulting in a cylindrical protrusion perpendicular to the sheet’s surface or at a specified angle .
An analysis is presented for the bulging by lateral pressure of superplastic alloy sheet that has a flow equation, in uniaxial tension or compression, given by σ = K ε ̇ m, where σ is the flow stress, ε the strain rate and K and m are material parameters. Two cases are dealt with: (1) the bulging of a flat circular sheet clamped at its .
Electromagnetic forming (EMF) is an uncommon metal working process that relies on the use of electromagnetic forces to deform metallic workpieces at high speeds. It is expected to overcome some formability barriers of materials. EMF process analysis is the foundation of theoretical analysis. However, the electromagnetic sheet metal process is very difficult to .

You MUST NOT enter a box junction unless your exit road is clear. But you can enter the box when you want to turn right and you’re only prevented from doing so by oncoming traffic. If there’s a vehicle already on the junction waiting to turn right, you’re free to enter behind it and wait to turn right – providing that you won’t block .
