Electromagnetic Forming Tools and Processing Conditions: Numerical Simulation

Sequential coupling simulation for electromagnetic–mechanical tube compression by finite element analysis

“…5. To adapt the high strain-rate conditions of the process, the quasi-static data are scaled by means of Cowper-Symonds constitutive model (Mamalis et al, 2006):…”

Geometric issues in V-bending electromagnetic forming process of 2024-T3 aluminum alloy

“…According to Fenton and Daehn [3], the requirements of energy efficiency and lightweight materials and structures are important motivation factors to study EMF. In addition, Mamalis et al [4] introduced that this technology has already been used in aerospace and automobile industries. However, the EMF process has not been thoroughly understood so far.…”

“…However, according to literatures, with the advantages of lower calculation cost and faster speed, the loose coupling strategy is widely adopted by researchers despite the loss of accuracy to a certain degree. As a result, Mamalis et al [4] advised the loose coupling strategy to be used for parameters estimation. Without considering the decay of electromagnetic force with distance between the sheet and the coil, the electromagnetic force calculated by loose coupling strategy is overestimated.…”

EMS-CO2Welding: A New Approach to Improve Droplet Transfer Characteristics and Welding Formation

“…The demands on new welding techniques, such as active flux [6], laser welding [7], resistance-friction stir hybrid welding [8], vibratory welding [4], and electromagnetic field hybrid welding [9,10], are continuously increasing. Although some new approaches have been proposed to improve the performance of welding joint [11] and property of surface layer [12,13], the gas shield arc welding technique still dominates the main welding manufacture fields.…”

“…With the use of EMS welding technique, the primary grain of the welding joint is refined [10,17,18], and the segregation and nonhomogeneity of the welding seam are reduced or eliminated [13,14,17]. Because EMS welding improves plasticity and toughness of the welding joint and reduces the sensibility of crystal crack and gas cavity [19], it has been called NO-DEFECTS welding technique by some researchers [9,10,14,17,18].…”
