In the process of electromagnetic forming (EMF), the rebound effect caused by high speed collision between sheet and die will affect the fittability, which results in a bad forming quality of workpiece. In this paper, finite element models of direct EMF and indirect EMF with an elastic medium are established, the influence factors of fittability in indirect EMF are studied, the two Cited by: 3.

The coil bending causes additional bending stresses in coil springs. Therefore the calculation uses the correction coefficient to correct the tension. The way of design procedure used in this book allows defining dimensions of .

This book is intended for students of science and engineering; it aims to develop both an understanding of the important concepts of physics and some analytical skill in . Those bellows are formed by wielding flanged and fluid plates together, thus creating 1, 2, or 3 U – shaped corrugations. ASME Code inspection and U – 2 stamp is required.
