✦ Synopsis

Dynamic and ductile fracture of edge-cracked beam made of Type 304 stainless steel under electromagnetic bending force is studied experimentally as well as theoretically. In the theoretical part, we calculate the extended J-integral with the effect of both electromagnetic force and thermal stress caused by the Joule heating concerning the fracture phenomena due to the electromagnetic force. In the experiments, the edge-cracked beam specimens of Type 304 stainless steel are fractured under the electromagnetic force, measuring the crack initiation time, the crack velocity etc. Finally, the theoretical and the experimental results are compared.
