Uniaxial Tension and Cyclic Deformation Behavior of Steel/Zinc Laminated Composites 2007-01-0996
Uniaxial tension and cyclic deformation tests of Steel /Zinc laminated composites made by casting were investigated under different conditions. The results indicate that the zinc/steel composite has increased plasticity and decreased strength when compared to steel alone. The strain rate has nearly no influence on the stress-strain graph for the specimens of composites under tension. The stress levels at ±0.5%, ±1%, ±1.5% strain range under tension and compression increase with the increasing number of cycles suggesting a cyclic hardening behavior of the material has taken place, which is gradually obvious with increasing cyclic strain. The stress under tension and compression tended to stabilize with further cycling.
