Due to size effect, the mechanical behavior of foil materials may be different from that of bulk materials.
Consequently, models and theories appropriate for bulk materials may not be applicable for foil materials which result in certain essential problems and phenomena occurring during the fracture process of foils must be explored experimentally.
The materials consist of a kind of pure copper foils with different thickness in hard state.
