Macroscopic fracture behavior of nickel foam under tension*
The tensile fracture has been macroscopically investigated for nickel foam under uniaxial tension. The samples of nickel foam with porosity of 88.29％ were uniaxially tensioned at various rates at room temperature, and the phenomena of tensile fracture were compared with that from the fully dense plate of metal nickel, so as to investigate the differences between their behaviors of tensile fracture. The results indicated that, nickel foam also displayed the feature of macroscopic plastic reform during tension, but it showed a macroscopic brittleness much more than that of the fully dense body. In addition, an obviously gradual course exhibited for the foamed body during fracture, and a rapidly instant course for the dense body correspondingly.
