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 .
