ABSTRACT |
The paper presents the results of forming rifts in five-layer fiber reinforced metal polymer laminates by electromagnetic
forming. During the experimental studies the discharge energy of the electro-magnetic machine was varied in such
a way as to achieve different depths of the rift. Samples obtained by electro-magnetic forming were compared with control
samples obtained by forming using a rubber pad under static loading. The strain state of the samples was analyzed using an
digital image correlation system Vic-3D. The experimental research of fiber reinforced metal laminates forming under the
influence of pulse magnetic field has shown the possibility of formability increasing due to change of strain state: the rift zone
is dominated by compressive circumferential strains, rather than tensile radial strains as during conventional rubber pad
forming. |
