Numerical Analysis of the Response of Thick Wires to Extreme Dynamic Electro-Mechanical Loads

R. Cunrath[1], M. Wickert[2]
[1]Fraunhofer EMI, Efringen-Kirchen, Germany
[2]Fraunhofer EMI, Freiburg im Breisgau, Germany

Research at Fraunhofer EMI addresses the response of materials in extreme dynamic loads. Besides mechanical or thermal loads, intense electric pulse currents also represent an extreme dynamic load. Experimentally, metallic samples, mainly thick wires, were electro-mechanically loaded ... Read More
