摘要：
Foamed metallic materials can be used as many structural parts. The tensile experiment was carried out on this porous body, and the elementary mechanism of the corresponding fracture behavior is analyzed in the present paper. It is found that the macroscopical fracture feature of this foamed metallic material with open cells differs not only from that of the transverse rupture by maximum tensile-stress criterion, but also from that of the plastic-flow failure by maximum shearing-stress criterion, and presents a complicated mode of fracture between these two criterions. The necking-down appearance was not observable during the tensile fracture, and the percentage elongation (apparent strain) resulted primarily from the plastic deflexion of metallic struts within the three-dimensional reticulated structure.
