Abstract
Interfacial control plays a role in micro-punching an amorphous electrical steel sheet stack. The punching performance was compared between conventional and resin-coated sheets. Through the tensile loading test of resin-coated sheets, it was found that resin coating increased the interfacial friction between adjacent sheets. The punching load decreased in every five-layered stack specimen with an interfacial resin coating. In every punching experiment, punching- affected zones were mainly governed by cracking near the punched hole. Bending deformation was enhanced by interfacial friction to change the original shearing of the stack specimen.
